Wow well done! It looked, sounded, and felt great. I wasn't sure if I was doing the right thing exactly, I think I was damaging the first boss but some indication of doing the right thing would help, but well done on the work, idea, and mechanics!
Thank you! I purposely didn't put a health bar on the bosses to keep it like Touhou, but I really should have set some time aside to make a tutorial level. I agree that it's hard to get the hang of.
