I enjoyed it! Not a bullet hell, but a beam hell?
Would be cool to see more than just beams as difficulty increases, tho.
I like the artstyle and music too!
I'm torn on the black character on the black background. It gives it visual style as it passes in front of the god, but if you're at the edges you miss out on the animation.
If you do go about fixing it, perhaps instead of a adding a background, you have a faint, colored outline that follows the player (but put it on a layer behind the god so it only shows up when in a dark area).
