- Waves have developed personalities. From wave 10 they arrive SWARM, ARMOURED or FRENZIED, and from wave 45 they have started turning up in pairs, which the health and safety board has been notified about.
- SPLITTING waves join at wave 20, once you have had a chance to get used to the idea of enemies at all. Splitting enemies divide when killed, because that is what division means, and they do it exactly once, because the alternative does not bear thinking about.
- Bosses are now four separate individuals rather than one very large individual wearing different waves. Meet COLOSSON, THE DUPLICANT (halves itself, twice), THE BULWARK (a wall with opinions) and THE HARRIER (fast, armed, rude).
- DODGERS have joined the roster. From wave 8, certain enemies have learned that standing still while being shot is a choice, and they have chosen otherwise. Your bullet arrives, they step sideways, and the arena prints MISS at you in a tone you will grow to resent.
- THE VAULT has opened. Rebirthing now mints Wangs, a permanent currency that survives everything short of a hard reset, and the vault spends them on eight upgrades that never go away: head starts, ability points, better XP, harder numbers, thicker skin, richer rebirths, fatter dividends and luckier draws.
- Rebirthing now unlocks things instead of only multiplying things. Tier 1 puts KEYSTONE nodes on the board — one node that scales damage, health, speed and XP at once. Tier 2 adds DIVIDEND nodes that pay out in Wangs. Every tier also lifts the value of every node you roll and quietly improves your ability draws.
- Offline progress. Close the game and the numbers keep going without you, up to eight hours' worth, at a quarter of the rate you would have managed in person. The announcer will tell you what you missed.
- An entirely new soundtrack, generated from nothing but arithmetic and regret. The menu drifts, the arena drives, and the boss theme is the arena theme after something has happened to it. No two notes were purchased from anybody.
- Every sound effect has been rebuilt out of studio equipment. Shots are calculator keys, purchases are split-flap boards, warnings are relays, and levelling up is the sound a very old television makes when it is pleased with you.
- THE WANGOPEDIA has been compiled. Every number, board node, opponent, champion, wave state and vault upgrade now has a file, and the files fill themselves in as you meet their subjects in person. Entries you have not encountered sit behind the static, refusing to comment.
- Wangopedia files keep your personal record against their subject — how many times a number has been offered to you, how many of an opponent you have met, how many times a champion has been faced. Anything discovered since you last read the section wears a NEW chip until you have had a look at it.
- SOUND controls have appeared on the MORE page. Music and effects are now separate dials, each with five settings and an OFF, so you may silence the studio computer without silencing yourself.
- The board no longer goes quiet after wave 24. It has been made to keep introducing itself.
- AUTO BUY has stopped hoarding. It was buying the cheapest node it could find, and since the four innermost rings all cost the same single point, it would fill all sixty-four of them before it would consider spending a second point on anything further out — where the numbers are, at time of writing, roughly twenty-five thousand times larger. It now works its way outward, buying breadth as it goes. Players who pressed the button were being quietly punished for it, which the studio regrets.
- Auto-buy also explains itself. With a filter set and nothing matching next to you, it used to pocket your points in silence; it now says which filter is the problem, out loud, in front of everyone.
- The tab bar is a row of proper illuminated console buttons rather than words painted on a strip, and the powerup counter now sits beside the word POWERUPS instead of hovering between two tabs claiming allegiance to neither.
- The opening waves have been made survivable by an ordinary person holding an ordinary number. Previously wave 1 required approximately eleven seconds to defeat and approximately four seconds to lose to, which the mathematics department has confirmed is the wrong way round.
- Losing to a boss now teaches you something. Whatever damage you managed to do is paid out as XP, so a wall you cannot yet climb becomes a wall you are visibly climbing, rather than a wall you are standing next to for the rest of your life.
- Sentry Digit no longer stops at four. Each additional copy raises the cap by two, up to twelve, and they now arrange themselves in tidy rows either side of you and fire out of step so it sounds like a workforce rather than a single very loud one.
- The old combat ambience has been retired. It has been replaced by actual music, which it had been impersonating for some time.
- The NumberWang! studio is now officially a studio. There is an ON AIR lamp, audience lights, a channel plate, and a news crawl that has been told to stop talking but has chosen mathematics instead.
- A professional announcer has arrived to explain your waves, bosses, level-ups, rebirths, and your terrible financial decisions. If you cannot afford something, they will let you know with a very disappointed beep.
- Confetti cannons have been installed. Nobody knows who approved them. Everyone agrees they were necessary.
- Numbers are now displayed on proper mechanical number machines. Every digit rolls over one at a time because that is how the ancient number people intended.
- Ability draws now arrive as full mathematical contestants. Seats, spotlights, dramatic lighting, and a suspicious amount of importance included.
- Sentry Digit has entered the arena. Up to four tiny number assistants will now follow you around, firing at 60% speed and dealing 50% of your damage. They have been trained in the ancient art of pointing at things and making them smaller.
- Damage numbers have unlocked the HUGE category. When a hit doubles your previous record, it becomes too large to behave normally and begins dragging neon trails through the mathematics.
- The background is now filled with a tasteful amount of falling numbers. The void was looking suspiciously empty.
- The announcer now has a much larger collection of phrases. Wangernumb, board rotations, shinty-six, Colosson, and the legendary 1974 Mathematical Act can all now legally appear.
- Bullets no longer disappear into the mysterious bullet dimension. They now fly away dramatically after completing their mathematical duties.
- The camera now moves like a professional number filming machine. It drifts, zooms, and pulls back during rebirths because bigger numbers require bigger vision.
- AUTO BUY has arrived. It spends your entire bank account from cheapest to expensive because apparently numbers are better when purchased in bulk.
- Auto-buy filters have been added. Choose ANYTHING, DAMAGE, HEALTH, SPEED, or UTILITY and allow the mathematics to make a slightly more focused mistake.
- RESPEC has been invented. All board points are returned so you can undo your previous mathematical crimes.
- Payout Nodes have appeared. Gold and rare nodes now return points immediately after purchase because giving numbers away is how you make bigger numbers.
- The board now keeps records of your spending, your ownership, and how far into the mathematical wilderness you have travelled.
- Locked sections of the board are now visible. They sit behind mysterious static screens, waiting for you to become numerically worthy.
- The MORE tab now displays important statistics including your biggest hit, DPS, crit chance, and every ability card you have collected. The numbers have been interviewed.
- The main menu now features rotating NumberWang! headlines, plus your level, best wave, and rebirth count. Your achievements deserve unnecessary broadcasting.
- The sound toggle now remembers your choice. A rare example of a number learning something.
- The Powerup board has evolved from a pile of numbers into a branching mathematical ecosystem. Some paths lead somewhere. Some paths lead to disappointment.
- Nodes are smaller, connections are clearer, and the board now looks like a proper machine designed to create suspiciously large numbers.
- The board can now see further into the future. Three cells ahead are visible, allowing advanced planning and irresponsible optimism.
- Zooming out now reduces nodes to their purest form: the sacred icon.
- The board now centres itself around your actual achievements instead of pretending the origin point is the most important location in mathematics.
- CENTER has been upgraded from "throw player somewhere vaguely useful" to "place player near their numbers."
- Tabs now rise proudly when selected. The interface has discovered drama.
- The MORE tab now scrolls. Previously it attempted to contain infinite knowledge in one tiny box. The box lost.
- Ability names now come from larger number pools, meaning your collection can become much stranger before it starts repeating itself.
- Rebirth was accidentally giving you back your old board. The past has been deleted. The numbers have moved on.
- Large damage numbers no longer get chopped in half by the evil clipping rectangle.
- Ability choices can no longer be rerolled forever until the universe accidentally gives you something legendary.
- Enemies now understand they should enter from the proper side of the arena instead of appearing directly in front of your face like mathematical jump scares.
- Knockback no longer traps enemies in an endless backwards journey. They can now remember they are supposed to fight.
- Ranged enemies have remembered they are ranged enemies.
- The game no longer lets you attack enemies who have not officially arrived yet. Their paperwork must be completed first.
- Combat warnings, boss bars, death reports, and other important numbers no longer cover your other important numbers.
- Level-up sounds no longer celebrate twice. One celebration was mathematically excessive.
- Nothing has been removed. NumberWang! 0.2 believes every number deserves a chance.
- Auto Buy can only purchase numbers currently connected to your mathematical empire. It cannot yet purchase things from the forbidden number dimension.
- Existing saves may experience some board confusion after payout nodes were introduced. Your numbers may have changed their addresses.
- Extremely large boards may become too powerful to fit on screen. The camera is currently negotiating with mathematics.
- RESPEC is new and is still learning the ancient art of safely undoing your choices.
