As always, I'm impressed with the number of bullets you can get on screen without even a hitch in framerate and this game delivers on that.
Usually bullet hells which do this end up being very cluttered and it honestly becomes hard to see what's going on but to your game's credit, the simple visual style and colour pallete made things very easy to discern and it looks really cool as a result
I really wish the player could take damage. Would have made the game a lot more fun and definitely one of the best XD. None the less, you have a solid game here man. All it needs is player damage. Great job overall :)
