IDK what happened but I wasn't able to use the mouse to click the buttons nor wasd to select buttons. ESC didn't work for me either, but finally started being able to play. I did get completely lost in solid black area and no matter what way I walked for how long I was walking I couldn't find any walls or anything to help me find my way out. After I went to close out and couldn't, my mouse was stuck in game. Had to alt tab to close it out. Is interesting concept, but knowing my own luck at finding unescapable areas that may or may not have ever been intended to be found is something I tend to fall into. lol. I remember finding a few areas in WoW that put me under the ground. Anyway, would be nice to having more control options like not only wasd but arrow keys as well. I'm a left handed gamer and arrow keys are much easier for me then wasd.
