That file here seems clean. There is a dll in it from unity that does some things that one scanner on vt takes issue with. Might or might not be about that unity tracking thing. That being said, there seems to be a lot of warnings for the download versions and the devs do not know exactly where those come from.
Worst case their development machine got infected. So maybe a bit of patience is prudent.
Anyways, an unknown and therefore untrusted dev's files should not be allowed to be executed, if there is any warning. Too many real scammers here. And the game is not really fleshed out anyways.
