Something that annoys me quite a bit and I see it happen with a lot of unity games. People leave the cursor enabled with first person or third person games. You can fix this with one line of code ( Screen.showCursor = false;)
The game appears to be bigger than the screen size allotted.
Neat concept and story, but the controls are much too sensitive to movement.
The audio fits nicely and the GUI was done well (apart from screen size issues) and I agree with Guennor's comment about needing to disable the cursor.
Also, I think you missed a trick here, because there could have been some gameplay in lining up the n.f.h. and taking them out en masse, but you only do hit-detection as far as the first neighbor.
It has pretty good mood. I liked the music and the look of the textured Unity-capsules, haha.
