Hi Jonathan,
My guess is that it's a memory problem, or an issue with loading the first scene. Guessing you have 2GB of RAM (2048MB), which is a bit low for the game. The recommended amount of RAM is 8GB. You would need to upgrade your RAM or try a different machine to be sure.
If you email support@itch.io and explain that it was bought by mistake, they might give you a refund.
Sorry that is not what you wanted to hear!
Cheers,
