I loved this game so much!!! The art style just fit the vibes so much and the music was so groovy. On my second replay the music stopped working for some reason and I was so sad but luckily I died and it came back my next replay lolol. I love the unique characteristics you give each boss, such as disrupting dialogue, different movement patterns, and different attack patterns! I also love how you use a scrolling background to really bring out the movement, though I will say the final boss one is the most trippy (but when you get really focused and into it that trippy feeling thankfully fades). I do wish the cooldown was shorter, since it especially feels draining when you're trying to replay and have to wait to regenerate. Maybe even just have a healing item or something spawn if you hit the boss twice without getting hit so you can have 2 HP quickly would be cool to award skilled players and not have them sitting and waiting. I would love the ability to speed run the bosses because of skill and not wait every 2 hits to regenerate another HP so I don't die just from hitting the boss! Also I was so sad every time the game crashed when I lost to the final boss hahaha maybe consider checkpoints? Although maybe the frustration is an intentional element, depending on how forgiving you want to be to players.
