Plenty of nice ideas, and a nice story!
The combat is extremely underwhelming but it does show interesting things. Namely enemies that back away from you while shooting, and the ONI MISSILE that also works as a shield. (good work on that one, made me laugh)
The selling point is clearly the story, it really kept me going. And then there's the "true ending" requirements, they aren't much but they're implemented in an interesting way. I just really liked how it was done.
