Great job! The visuals have a great style to them and the music fits the game very well. The music and sound effects really work well together to give a feeling of being in this big, cold, cramped factory. I had fun exploring around.
I initially was really confused by the controls (More than I probably should have been) and was turned off, but I actually think I like how you have them set up. It's an interesting combination of tank and mouse controls that I don't know if I've ever seen before, once your used to it it feels pretty natural.
