I found some things that need atention:
1) i have random flickering in game (GTX 650 Ti, but i can run 95% strategy game without problem)
2) rotation (with middle mouse button) is too fast and there is no way to set it to original position (like small "North" arrow somwhere on the screen)
3) when i want to build some building it shows me "you need to place it on road" (or something similar) but it overlap description, try to move it a little bit
