Oof! I mean, we think our games are safe.😁
The ones you can download from itch.io should be safe.
For other versions you can find in the wild, we can't really take responsibility for those...
Can you tell us which version and platform you've tried that got flagged as a virus?
If it's on Android, it could be due to us not being "certified developers" (we have to pay Google for that privilege🙃).
That could be the cause, but it would be a false positive in that case.
Same thing could happen on Windows or macOS, depending on your security settings, we suppose.
