Good job guys, it was an interesting idea to explore, it's sad you had a rough week though.
What i would suggest as one of the priorities for a 3D game would be a settable mouse sensitivity, i know it can be a pain to implement rather than focus on the game but it was really frustrating for me to look around
Also with the game, i got disoriented a few times when i respawned, that's because there are no visual cues, one single object in a scene could fix that, and is just a matter of adding an object
Anyway once again, nice job guys!
