Fantastic game. Very nicely done.
Only thing that's less than perfect on the PC version is the control scheme. When selecting grid squares with the mouse, something in the screen-to-3D projection is wonky. You generally have to click a ways above a square to select it, but how far above varies, so there's a lot of trial and error.
The keyboard control is better. Don't suppose there's any way to redefine the keys? It's mostly arrow keys and enter, so my left hand feels neglected.
