Great visuals and atmosphere. Good interpretation of the theme. I like most of the mechanics here except the recharging got tedious quickly.
My biggest problem is that the grid is half the size it needs to be to make the game feel "right". As it is it feels like the grid was slapped on after the fact and not something the game was designed around. Also the mouse look must snap back to 90 degree angles and also be an optional thing, like if you press and hold a button to activate it.
