I really like the sprite work. The jump and the camera shake after shooting are really satisfying and the concept is very original! Maybe making the logs fall progresively faster would make the game more challenging but in it's current state is fun too.
The lack of sfx or music is understandable, since 3 hours feel like a handful of minutes when making a game (I had the same problem >_<).
I would love to see this ported to mobile after a bit of polishing! Great job!
