This game has a ton of potential, like probably the most of all the games I've played so far, the style and atmosphere is really really good. But I did find some bugs, firstly the mouse sensitivity is related to player rotation, which can make it quite hard to aim. I also got pushed into the walls by the enemies a few times, which I couldn't get out of. Also I'd make it more clear in the upgrade area that there's a door you need to go through. This game is really cool though, I could easily see myself buying something like this if it was more polished and fleshed out.
