This is an interesting approach to the topic at hand. I enjoyed the music and the minimalist approach to the sprites. My biggest problem was that I was struggling to understand how to actually hurt things at first. Many pieces of the UI became very hard to pick up after I tossed them the first time. Additionally, I thought I was suppose to throw the pieces at enemies but I had much more success just dropping them on enemies instead.
All in all, this was a fun little game. I hope you learned a lot in this game jam!
