Great boss rush! Mimi seemed way easier than bosses like Nexa and globeh, but that might just be a skill issue. I like how unique each boss felt without being boring. Having several attacks that constantly rotate definitely added a lot of chaos and challenge to the game. If I had to give feedback on how to improve, it would be to increase the sightreadability of bosses, like with Deton not really showing impacts. Putting something like a shadow or an X could help give a higher chance to dodge without making the boss literally easier. I would also try to fix some bugs. I noticed that if you hugged the right wall, you could dodge almost all of Mimi's attacks. (I was able to cheat impossible difficulty using this.) I haven't tried on the other bosses. I played the game in browser and without sound, so I may not have had the full experience, but I still highly enjoyed beating all the bosses.
