I agree with some of the other comments about the uncharged attacks, I think they could be sped up a bit to be made more useful.
I also think it would be helpful to have an indicator for enemies that are off screen, since they can charge at you while you can't see them, forcing you to kite them towards the center of the screen to be able to see and hit them. Or maybe only allow them to charge at you while visible on screen.
And again, seconding reducing the speed boost granted when an item is picked up, since it just ends up hindering the controls in most cases.
But the music and SFX in game is great, and its got solid foundation to build into a great bullet hell/touhou style game, nice job for only having two weeks!
