Hey, I just played your game. It doesn't suit the theme but I'd say it still was a pretty cool game. I have some feedbacks which might help you improve your game next time. Note that these feedbacks are just for improving your game and doesn't mean the game is bad. Feedbacks:
1.) Make the player movement more responsive.
2.) tweak the gravity.
3.) apply friction
4.) Indicate that the game is based on timer
