Amazing. The upgrade system is really fun, when you're having trouble with a mission choosing your loadout specifically to overcome it is very satisfying, but even aside from that, it's just an extremely solid shmup all around, the controls are tight, the patterns are beautiful and flashy, every level is a different awesome setpiece, and it's difficult but not unfair. The only thing that's kind of annoying is the characters constantly talking during gameplay, but you can turn it off, which is nice, especially after your first time through a level when you've already heard all the dialogue. Don't turn it off for the final boss though, cuz there it's amazing. Even though I complained about the voice acting, I actually really love to see a shmup that makes an effort to actually tell a story with characters and dialogue.
