Great game!
My only qualms while playing is that the default keybindings often takes me out of the zone each time I want to use a special skill since I have to put my hand in an awkward position to do so. Completely breaking my flow, which is albeit ironic considering the skills page is called "Flow".
One more thing, Caps lock + RMB attacks feel redundant since I can close the gap between myself and the enemy with Q anyways.
Good luck with the game!
