I'll update this after i get a chance to play, however, as of now I have started the game, clicked the settings in the lower right, then close in the lower right and the main menu is just...gone XD Figured I would let you know
EDIT: Played it and I actually like it quite a bit! I'm excited to see where this goes. Still obviously rough, but it's still young. A note I do have is in the menu in game, i would move the "Exit Game" somewhere else, it seems to be in the place that a "Return to game" button would be and has given me a few moments of "Damn it" XD
