Love the art style. It took me a little while to figure out what was happening with the exchange moments, but it works. I think my feedback mostly has to do with the boss designs, some of them felt annoying (sirmaau was the hardest, the sky turtle one was super annoying to track down)
I think through all of this the camera was the biggest enemy making it hard to see when attacks were coming, or when things would swap randomly (golem) or exit other colliders and hit you (esperh [herpes??], worm). I would’ve appreciated a way to heal when it kept swapping me back to sirmaau :)
