Pretty fun(not too dissimilar to my own entry, actually)! It feels a little... easy? It seems like you can just go around in circles until you're comfortable with the group of enemies you have, then close the loop somewhat easily when they're relatively bunched up, and it didn't feel like I had to change my approach much on the Pain difficulty. It feels like I got hit most often by enemies that spawned in the direction I was moving. The most challenging enemy in my opinion was the pink square with the tricky movement; the orange square was probably the easiest despite being introduced a bit later, as if it should have had more hit points. Getting another dash every 2000 points is actually pretty smart, since it encourages taking out enemies in groups whenever possible, even if you're not playing to get a higher score!
Pretty good!
