I'll try to keep this short to not bury your movement explanation comment!
This game is so fascinating to control! It requires some patience to get used to but once you do it's so rewarding! I like how spaced out the boss attacks are. As you play the game, you do have some breathing room to read the screen, formulate a movement plan, and then execute it. Once you do and pull it off, this feels very satisfying, the pacing was just right for that I think! The attacks were very well telegraphed as well, I can tell you put a lot of thought into them.
I echo that previous comment about the orbit display when it gets too large, but I totally get how time constraints might have gotten in the way of that getting fixed. I also kept wondering about the choice to not immediately kill the player if they went out of the screen's boundaries but I see now that it was probably to make sure they had some chance to teleport back to safety
The music was so nice it almost felt like a reward listening to a new track after beating each boss heheh
