are you on mac or windows? and do you have 2 GB of free ram available to run the game? if the answer is no to the second question then you can't run the game in it's current state. The team will be working on optimizing the game more in the future. But it can't be update now because judging is still going on.
It was exported as a Windows Desktop Program and not a Universal Windows Program, so that could be an issue if WDP is for windows 10 and UWP is for older windows versions. (until judging if finished we aren't gonna do anything but the moment that is over we will put out an updated version to fix a few bugs and this issue. sorry for the inconvenience.)
