I liked this a lot! Killing the enemies with the laser beam was really satisfying, yet there were enough of them around that they felt like a threat, especially because they would lunge at you. Only thing is that it took me a minute to realize what to do. I didn't realize that I had to hold E to unlock the server, and then, since I didn't see any indication that the door had opened, I wandered around for a little while longer. Likewise, in the second level, I didn't realize there were multiple servers, would've been nice to have some UI indicating how much servers were left to connect up. Other than being a little bit confused, I really liked it! The lighting in particular was very well done and atmospheric.
