The parry mechanic feels awesome! I did get past the minotaur, but the next boss (chimera) bugged out for me. At some point it transitioned to the "rest" state (according to the text above its head) and never left that state so I had no projectiles to work with. I also started taking damage from a spot on the ground somewhat above and to the left of where the chimera was resting, and I'm wondering if the collision and sprite got desynced or something. I also couldn't beat the minotaur a second time (not because bugs, just skill issue), adding a checkpoint after each boss would be helpful. I also noticed on the minotaur that I was sometimes dying despite having hearts left, and at some point he dealt 4 damage at once, after which my screen gained a permanent red hue. I apologize that my comment devolved into focusing on bugs but I wanted to mention them because I love what you have going here and look forward to seeing it continue to develop!
