I couldn't decide to add online to the game for a long time, because sometimes my knowledge wasn't enough to display "Hello World" in the console, but now it seems to be working.
Each player will have their own personal record, which is saved at the finish, as well as their own personal start time. For obvious reasons, the leaderboard is the same for everyone.

I redesigned the UI so that the information doesn't cluster in the center, and I also added tooltips to the left corner.

Essentially, this is a major update, and because of the online aspect, I now plan to create maps and move on to developing a new game.
