Welcome to an overly complicated compilation of my 2-player games, some new, and some older than my Scratch account! There are far too many instructions. I'd have to write an essay, only for nobody to read it. The basics are that the games are controlled with some combination of WASDQERF1 space for player 1, and arrow keys and JKLNM for player 2, although most games only use a few of these buttons. Most games are simple, with usually only movement plus one other button, but one game uses all the controls. The player on WASD owns all blue tiles, and arrow keys owns all red tiles. WASD goes first by clicking on a red tile next to a blue tile in order to attack it, and the winner of the minigame that follows gets to keep that tile. As games are played, points are gained in a fun pattern (loser gets most points in middle tiles, winner gets most points in back tiles) and can be spent by pressing number keys as shown on the menu in the minigame select screen. You win once your enemy has no tiles left and no way to gain new tiles. Seriously, that's just the basics. The rest is left as an exercise for the reader.
You can probably tell by the quality that I only made a little bit of the art for the main menu, and relied on text-to-image models for most of the tile art. If you can actually play this against someone and have fun, I'll be impressed. Most of the people I play this with have pre-existing exposure to my old 2 player games, as well as having me there to explain it.
