Nice to see another bullet hell!
I found the game to be very confusing overall. It's hard to understand the bullet moving patterns, because some of them look the same, despite behaving differently. There's also so much stuff in the interface. I think the weapons/shields/energy system is interesting, but there is no time to properly learn the mechanics, since the player is instantly thrown in a challenging battle.
The sprite art is pretty good, the GUI could use some work though. I noticed a sound slider in the menu, but there wasn't any sound in the game, is this a bug?
I think the game has potential, it just needs polishing.
