I did not get too much time to balance, so it is quite hard, but definitely possible given how reflectors block all damage. My record so far is 1/5 hp. I will try to expand the tips section at the bottom since I think a specific approach is needed to be able tackle this boss. If this was a souls-like(ish) game, this boss wouldn’t be an issue, but in the case of a jam, no one is going to spend half an hour to beat a singular boss.
Anyways, thanks for playing! I will likely release a follow-up patch after the voting phase to include a few tweaks and improvements.
