ESC2 Die (restart)
ESC3 Get out of fridge (quit)
ESC4 Set speed (resets settings to defaults for speed, vsync and "show real pieces")
ESC5 Players (sets the players to 1, which freezes player 2 and seems to make them edible? Player 2 comes back in if you make it to level 2)
ESC6 Icon size (resets the tile size to the default 8x8, but doesn't regenerate the tilemaps leading to weirdness if you started with a different sized tile. I'm not sure why this exists)
ESC7 New background (generate a random psychedilic background)
