That is a very interesting idea! However, it is definitely too short so maybe add more levels?

Fun little game, definitely needs more levels though. The lighting also seemed a bit strange as your approached the tree.

Cool little game, very short and would like if more levels and mechanics were added. Well done!

The mechanics are fun, but it could really use more levels or perhaps a random-level generator. Good idea!

The implementation of the theme is really clever. One thing I'd recommend for improving the game is adding more levels and adding music(pixabay.com is a really good source for copyright-free music). Additionally, minor critique, but I'd recommend adding more lighting
