After playing this game for 3-4 minutes straight, when I'm returned to the menu my eyes are all messed up. Like the still screen is continuing to move. 5/5.
I love bullet hell games, this sort of fits that bill. It hurts my eyes to look at, though. My color blindness may have something to do with that though.
Fun game. At the beginning I just couldn't help but feel like I should've been filling in the spots that the numbers weren't representing, as opposed to the other way around. 4/5 for sure.
