Great game with a few problems
this is a real time strategy game so...
1) units should respond quickly (and the double click thing to deselect really irked me)
2) I should be given some idea of how strong a unit is (ie give the basic stats when you produce them)
3) scrolling should be easy
4) HOTKEYS. I shouldn't have to press W and a number at the same time, There should be a cycle unit key (always lost track of those froggers) also the buildings should be hot keyed as well.
Otherwise a clever game concept
