A bit sparse, as I'm sure you know, but it functions fine-- except for movement. I thought it was my controller, but I unplugged it and I still kept moving backward. I think it may have remembered the state the stick was in and kept it. There were also a good few things with what I assume is the default texture with letters on it indicating faces, if that's not a mistake I recommend covering them with a placeholder texture.

It's rough, but it seems like you've got a decent base for a shooter here. Keep working at it!

Also please lower the amount of sway while walking in Glasshouse, it's a bit excessive.
