Hey there. I tried out the demo. Although the game didn't need to include the "Set Buttons Manually" feature, it does work properly. I disliked the fact that the game imposes its own controller profile, *before* you create a manual one, regardless of whether the controller is an official Xbox one, or a generic.
Beyond that, everything about the game looks and sounds great. I am tempted to endorse it on my new site, conflexgames.com
