Very fun game, it looked very polished despite the absence of sound (which is understandable considering the amount of time you had). You found a smart way of using the theme of the jam that added a good challenge and I liked that the dash pushed the enemies, it was a nice touch (one small issue was that once I managed to push a slime behind a wall and had to wait for it to come out to kill it).
If I had to recommend a few additions, I believe it would be nice to be able to see your stats in real time (unless it was your goal to let the player use their instincts and memory). Maybe another stat like bullet size could be cool when you have to deal with swarms of enemies.
Anyway, really fun game, great job :)
