For only a few hours work, it sounds like, a good effort. I think "snake but you play as the apple" could work quite well as an idea but I think right now its a bit too easy to force the snake to go back in to itself - just move parallel to the snake and reverse direction and it'll kill itself. It would be a simple fix to fix that but I think there would be the issue of the snake being too good in getting you. Maybe the best version of this game plays more like Pac Man where you're in a maze and the snake has a personality where it isn't always trying to kill you? Hmm, not sure, but you've inspired me to think about it.
