Oh it's a great effort for only 2 days! I love the simple idea because it was quite addictive and hard to stop. Kept replaying. An addition that might help it be more fun if you want to develop the idea further is a way to figure out where the next tile be. Or maybe make the colors visible but cycle through differnt colors for each one, then the player has to time their move to a safe tile. Anyway, well done.
