It's a great shooter foundation, but a lot needs to be tweaked. It would be nice to have a mouse sensitivity option and a fullscreen mode to begin with. The AI is merciless :(

Feels like a good foundation for a bigger game! Loved the enemy designs too!  :D I think maybe you need a bit more direction to guide the player to their goals. 

Fully implemented FPS controls. Detailed environment and enemy.

Unfortunately, I was unable to figure out where to find the key. There were no visible indications (the darkness, while atmospheric, made it even harder to navigate), and there was no HUD to point me in the right direction. I made 4 efforts and got killed repeatedly without figuring out which way I was supposed to go.

I liked the setting, it was really well put together and really felt like you were on an alien planet :)

Overall, an entertaining game. I like the setting and the mechanics work well. I think the alien AI is a little too persistent, but it isn't that bad.
