Be careful with this game, this remains the only game I'm 90% the false positive this .exe threw was actually a remote code execution virus. I don't know if it's been fixed or identified by then but about a week after, I had an incident where about $700 worth of games were bought from my account and gifted to chinese accounts at like 3am.
Luckily Steam is the most pro-consumer company on planet earth so they were reversed within a couple days but while I can't tie it to THIS game exactly, it was a little too coincidental that it was chinese steam accounts.
