I really really like the look of this entry (That background music is good too). The kind of grungy palette, the reflections and the clipping of the ground texture. It's visually very striking. The enemies are also weird and cool looking, and they rapidly gyrate in a really unsettling way (A good unsettling way).
A couple of issues. I couldn't figure out how to exit the sign popup, I stopped being able to move when attacking once, and I seemed to be getting damaged when there was no enemy around.
Would quite like to explore this world a bit more if you release an after jam version. Nice work!
