Not normally into shmups, but this was good!
Even casual mode was pretty hectic. Was a bit hard to tell what you need to get and avoid sometimes, since there was so much on-screen at once. I liked the power-up/upgrade system. However, it seemed like the second time I got to the upgrade screen, mousing over the disabled icons wouldn't tell me what was required to unlock them. (Not sure if that's because I already selected and bought other things or not.) That's my only complaint, really. This was nice and entertaining!
