Pros:
- A first-person, open-world game with items, action bar, movement, multiple locations, in 2 weeks? Hell yes!
- Multiplayer? Voice chat? You're a beast! (didnt test it, but I've done a bit of multiplayer dev - it's hard!)
- Love having things like a pickaxe and a rifle with animations and lighting and such
Improvements if you had more time:
- To be able to actually use the pickaxe
- That the bullets have some effect on things you shoot
- More storyline
Great effort though, one of the best efforts I've seen so far!
