Are you using the Itch desktop client? It has a built-in sandboxed environment for applications: https://itch.io/docs/itch/using/sandbox/windows.html
Hi Noun, Thank you for the solution you've provided. I believe an itch.io virtual machine could address such issues.
Also, thank you, Raconteur32, for your interest in our game. However, this isn't any "HIGHLY suspicious" file. It's merely an encryption done using the default method provided by the encryption software we developers use. After all, we don't possess the technology to develop viruses. If you feel it's inappropriate, please don't hesitate to delete it.
Thank you again for your interests
