No, the game runs at a set 1920x1080. I can quickly add in the ability to size down the window to 1280x720 (the games native res) but I definitely want to look into scaling the game for screen size.
Hey I just updated the game, I added an ability to toggle among 3 resolutions-1080, 720 and a smaller one, 648. So hopefully that alleviates that Issue. On the main menu hit Y/Triangle on your controller or S on the keyboard.
