Neat concept. At some points the stages were a bit frustrating (bullets which should've passed me instead killed me, enemies spawning right behind me without any indication), and the stages got a bit repetitive, but overall it was a fun experience.

The story seemed like it was trying to say something, but even though it didn't, I would not consider it pretentious. I still enjoyed it for what it was, but I do wish they did more with it.
