We had some problems with being able to walk through walls and with enemy graphics disappearing:
The mini-map was a nice touch and we spent most of the time looking at that to move around. Good variety of monsters and scenery elements (walls, trees, etc.) that meant you always had a rough idea of where you where from the 3D view. Did you make all these assets during the week? If so, kudos to you, that's a lot of work, even though they're low poly. Well done for submitting your game, it has some potential.
