This world is centered around you. Nothing will move unless you do. (I call it real-time turn based gameplay)

Q, W, E and A, S, D to move on the hex grid
R and F to switch weapons for the left respective right hand (if you have more than one)
Left and Right Mouse to use weapons
1, 2, 3 and Spacebar to use special items

Warning: 
Some firewalls will complain that the game wants to install dwmapi.dll. 
I haven't found anythin malicious in the game, but I also encountered no problems if the rquest is blocked, so do that if you want to be safe.
