Wow, that was really good. I found it highly enjoyable, and the (more or less) sync to the music feel is amazing. My only criticism is that the boss fight felt a little too long and reputative, but I still really like this one.
Thanks, I'm happy you enjoyed the game! Previously I wanted to add second boss phase after loosing half of the health bar, but now I think without time for this feature, I could chop out the health by half to avoid the repetitiveness, thanks for the suggestion, I appreciate it.
