Ha, I can see how you went in a different direction with a similar idea. :) I don't mind the simple graphics, especially considering it's a solo jam entry. Maybe you could take this further into a game similar to PAKO Car chase simulator? Or maybe something with airplanes/spaceships, since you have more room and speed to play with for some really interesting interactions, all sorts of weaponry, armour and the like, but still with the same switching theme. Gotta say though, the game got strangely laggy in the second level, I played it about 10 times, got to like 3200ish score. Not unplayable laggy, but slightly unpleasant none the less.
