I like the overall aesthetics in this on a lot. The music is also really fun and the mechanics are super straighforward and easy to understand.
There were a few things that could be improved, like the player being able to just leave the level at the borders or the tree trunks being a bit hard to distinguish from the ground at times. I would also like to hold down the mouse button to attack continously instead of clicking rapidly.
But all in all a fun and promising game! :)
