I'm going to update it in the next few days to make it not so jittery, and I'll make the game go full screen. I'm also going to make it so the tan and grey tiles switch colors when they flip upside down, which it used to do until I changed the code a little bit, which made it stop working. I think that's about all I can update without getting in trouble for adding more content to my game, since it's a game jam entry. I might switch the 1st and 2nd levels since I think the 2nd level is actually easier. Expect an update within about 3 days.
