Took me a second to figure out how to loot stuff. The 'E' key.
I think the idea is solid. Plenty to expand on. The music when you break into the building is mood. The style of the environment models is cool; minimal yet detailed. And I love the mix of a 3/4 iso camera and 3D models.
The timer is a real short. Also I think it is bugged, several times it went negative and I guess I could loot for ever?
