I liked the concept of this game, but it seems like there needs to be a few minor improvements. It seems like maybe the different control sets should be randomized every time you play so you can't just memorize the order. However, if you did this, you'd probably want to give the player a short break to figure out what keys to press next. Your current system works because you can memorize the order of layouts, so when the switch happens and there's no time to think it doesn't matter since it's memorized. I think if you want a more arcadey feel you should go with the randomized option, though. Nice work, I had fun!
