You should use the Itch application game launcher -

You should run all games in the Itch application game launcher while being sandboxed.  

Sandboxie is easy to use -

and Itch has their own sandboxing utility -

And of course you should always be running an up to date malware detector.

I do wish that people would take malware more seriously, gaming without full protection and running any unknown program can instantly disable and ruin an unprotected PC.

We are looking into how to fix the virus alert that sometimes appears while playing the game. Thank you.
