This is really good! Very simplistic, pleasing aesthetic/artstyle, it works very well! I like the movement, and the dash feels nice with the invulnerability, after-image, and screenshake! I think this game has a great learning curve for the speedrunning side of things :) It was really hard to aim in the boss fight due to the gliding movement, but I suppose that too is part of the learning curve haha
Good work on the SFX as well, though I'd say there could've been a few more like dashing and shooting, but really nicely done for this short timeframe!
Well done!!
