Fun game! Graphics and audio are nice. I couldn't figure out how to get to the tops of the trees on the forest level, but that's not your fault :P.
I kind of like how you don't take damage when touching bugs, but at the same time there's no incentive to be careful in platforming. Tricky tradeoff, but in the end I think you made the right move.
Biggest complaint is the collection of bugs is a tad wonky sometimes.
Overall, nice work!
