I really love this game's concept! Immediately the amazing artwork really drew me in, and it definitely nails the theme! I did start to have issues with the controls and camera at points, mostly with the camera getting caught in weird places, but other than that this game is really fun visually. The boss designs are super cool, and the ability to see info about them in the menu is a very nice touch!
Unfortunately, at least when I played, I didn't have any audio. I don't know if this is a bug or if the game doesn't have any sound, but if it doesn't I think some added sound effects or music could help give the player some more feedback during gameplay. That definitely doesn't stop the game from being fun though! I had a great time playing this and would love to see where it went if development continued.
