Attacking is really smooth and it looks cool. My only criticisms are a lack of dash immunity and a small glitch that killed me several times. The beam attack is cool, but not being able to dash through it makes for some awkward positions. Additionally, there is a glitch at the end of the beam attack where the boss returns to locking onto the player just before the laser dissipates. There were a few times where I maneuvered around the eye and as the animation ended, it would instantly turn towards me and beam me.
Overall a really cool game, good job!
(Also if you have a free moment, I would really like it if you could give me some tips on my game, I'm planning on remastering it and possibly selling it on Steam, so any input would be greatly appreciated)
