Very nice presentation, I like textures, enemies and reloading animations. Wood textures, desktops, overall quality of them is very high. Unfortunately environment could use a little more variety. Right now we're walking through coridors and mostly empty rooms, shooting enemies that pose to us no real threat. For most of the time I've been using the basic pistol, which is probably the deadliest of them all. Killing enemies with one shot, guys with shields with two, while assault rifle is either imprecise or does only quarter of pistol's damage. Shotgun is better, but only in close quarters and there's just not enough ammo to enjoy it. There's actually very little ammo pickups and for the spaceship that had human resistance present, it looks amazingly clean.
I was missing sound effects of pickups the most. Every time I was expecting to hear small "ka-ching" or to screen to get a little brighter for a split second when picking up ammo. Currently I had to look around to check if I took it with me.
Picking up diaries and reading them is one thing, but to read a novel that is describing what people do and how they feel is something different. I don't know if creating a narrator that describes how a person thinks and reacts is gonna work. It's out of character, unless these texts are excerpts from actual novel that exists in the universe, but somehow I got feeling it was about real people and describing real background of a conflict.
I can clearly see enemies but they can't see me and I can't shoot them if there's a short obstacle like a medical bed (?) between us. There's also no indication if we're being attacked. You can also shoot from the gun before it shows in your hand after reloading, shooting animation plays with a delay too.
I have to say that the game is somewhat lacking. It tries to be something like system shock but has little to no exploration. Then again, it plays mostly like Doom, but for that it's too slow, enemy and weapon variety is also pretty low, enemies can be killed too fast, walk too slow, their projectiles are also moving pretty slow. I did second run on the hardest difficulty and I haven't noticed any significant changes.
You have something interesting here but there's a lot to improve.
