I enjoyed this a lot. Once I found the logs I felt so tense, not knowing what was going to happen or what I would find. The ambient noises of the spaceship being the only sound pretty much through the entire game created so much atmosphere, as did the incredible visuals.
The game reminded me a lot of the original Persona: Revelations and it’s dungeon crawling screens, although I must say I prefer the quick movement of your game compared to that of older ones in a similar style. I would’ve liked a better transition between angles though, because the sudden switches were somewhat offputting when moving through lots of tightly turning corridors, or places with a lot of intersections. However, considering there is no map I found it fairly easy to navigate, without getting lost (although a map would be nice).
Considering on the game page you’ve said this is more of a test than anything else, I think it’s really solid. Some cleaning up would be nice, but you got the eerie feel I think you were going for. Well done :).
