Full run – the game can be finished start to end: 13 rounds, four bosses that come back risen near the end, and a bonus round against the sardine school
Final round – the school stacks up and speeds up over time, the camera pulls out to show the whole ring, and a banner shows your progress
Risen mode – beat the game to unlock it: the chick runs much faster and takes double damage, and it lasts while your combo stays up
Repeat bosses – bosses that come back re-emerge, reset their pose and AI, and in rounds 9–12 spawn already risen
Sardine school – no longer bites or charges while a boss is entering or while you're reviving
Bonus round – could never be won, the end banner never showed up
Round 1 – no longer crashes
Timer – the match no longer starts with the clock stopped
Fence – showed up as a pink and black checkerboard in the published game; it now uses its own wood texture
Revive arrow – the arrow around the mouse was missing in the published game, so players didn't know how to revive
Arena – the sand's roughness texture now ships with the game
Third-party packages – the game no longer depends on any external package
The sardine school can still hit you in the short gap between one boss dying and the next one landing
Bosses in rounds 9–12 have much less health than earlier fights, so the last rounds are the easiest
Risen mode only unlocks after finishing the game, so most first-time players never see it
Control hints (MOVE, STRIKE, GUARD, DODGE) show an empty box instead of the key
