Oh hey this was pretty sweet. It's very simple of course, but as you said yourself, it's already pretty fun as it is. I like the idea of the game, even if it doesn't fit the theme alll that well imo. I also really appreciate the way you got to balance the difficulty that would be to actually dodge all the bats with the fact they have a little delay until actually dealing damage, that made doing shenaningans to outsmart them to feel very satisfying to do, specially on the end when there were several of them and only a few chopping left.
Only nitpick I really have is that I think it's not clear were on the tree is choppable or not, since as far as I've noticed only certain spots are able to be chopped even among the already brightened parts of the trees (or maybe I was just not holding the button down for long enought, I really don't know). Other than that the game is really just too simple for me to be able to give any critiques tbh.
