There's something here: it's atmospheric and certainly has the makings of something quite creepy. But I found I didn't really feel like anything I was doing was having any impact in the tower defense section. Trying to engage with the meta-narrative and shutting the terminal down seemed to change things, but not in a way that made much sense, and repeating it made the game quite unplayably laggy. I think I would have liked it a lot more if I understood what I was doing?
