EDIT:
Tested it more thoroughly, multiple files get flagged by 2 antivirus providers, usually when u get 1/2 flags its a FP, still it shouldnt get any. Run this kind of games sanboxed, in a virtual machine or in an air gapped machine.
EDIT2:
I also sanboxed it and seems fine so most likely a False positive, still i dont recommend running on the main machine, run only 0/0 scores and sandboxed with tools like sandboxie, malware can be tricky to catch specially with signature based software.
