Play on turbo mode by pressing shift before hitting the green flag. This is mostly NECESSARY to play this game. Um.. So how to play this stupid thing? Hue and Dark buttons change the hue and darkness of the blocks you place. Blocks of different colours will try to convert surrounding blocks to their colours. Click the black square to place walls, which block out anything. That's about it.
This is just a stupid tile experiment I was messing around with. Might add more stuff later, or might not. Enjoy making red fight blue, I guess. Looks like red's winning.
