Important update:
I'm not saying this to alarm you, but Malwarebytes listed the game, the zip file, and the appdata files as trojans. Several of the scanners on VirusTotal also brought up trojan flags.
There aren't that many, and several are heuristic or AI driven. This isn't my area of expertise, but there's probably something in the code that superficially resembles virus behavior. However, you probably want to scan your system to make sure you don't have anything, either.
Thank you for your time.
