Quite a fun little experience! I thought the tying of the control scheme to the theme was a pretty neat idea. The simple controls also lend themselves well to a mobile environment if that's something you're interested in. Your visual theme and consistent art style were spot-on, and I really liked the arcade feel! The difficulty didn't seem to scale super noticeably, but you only had 48 hours to go from nothing to full game, so I can hardly blame you for not having playtested and balanced it to perfection :P
Overall, a neat little game!
