Very nice looking game. Graphics are good, though some assets look a bit out of place.
Liked very much the code-searching element, and the in-world map is also very good. Makes good use of the ability to look around. Reminded me of Doom 3 in a good way.
Overall good gameplay, but very small grid tiles make movement and navigation look a bit strange. The humor here is not my cup of tea, but it's a very subjective thing anyways.
