The bosses in this one are pretty cool, I like the variety of attacks that they have. The pixel art is solid too, although I think the blurriness on some sprites is a little off-putting. My main grievance (haha) with this game is that the controls felt a bit awkward at times and I do wish the boss attacks had a bit more telegraphing/build up to them. Sometimes it just felt like the bosses were pulling things out of nowhere.
Also, it took me quite a long while to figure out what I was supposed to do during the low gravity phase on the 2nd boss. That attack is a cool concept but some sort of indicator for people who haven't figured out the parry mechanic/don't see the random floating blue projectiles would help out a lot.
Anyway, good entry :), would be curious to see what this would look like with a ton more polish
