Really fun concept! I liked the combination of sketched 2D billboards with the simple 3D environment, you effortlessly create a stark contrast between the level and the enemies.
One thing I had trouble with was hitting the enemies. Although dashing through them works, a lot of times I found myself dashing just barely in front of an enemy and getting damaged instead. Maybe a grace timer after a dash could be implemented to make it more forgiving, as well as larger enemy hurtboxes.
Despite that, the game is super fun to just run/dash around in and explore the three levels that I was able to beat! Great job on the jam and good luck!!
