Thank you ! I definitely overscoped in term of animation which took a lot of my "making art" time, so I didn't have much time to make the level look different, but that would definitly be a good way to improve. Also I totally agree with the problem of not being able to push enemies vertically, which can lead to waiting for enemies to move, which can be boring. I was thinking of adding an upward and downward kick post jam.
Thank you for your feedback !
