I'm not sure this game functioned correctly on my computer... The UI was totally broken. The button to start was like a single pixel tall strip. I can't tell if the walls were just meant to look strange, or if my game graphics were all bugged out too. But this sort of thing happens, it's hard to bug test for multiple types of computers even when you have months to do it. In just 48 hours, there are sure to be some issues somewhere.
My main suggestion would be to put some sort of divider in the middle of the screen. It was a bit disorienting without one.
