It looks like a false positive.
From what I can see, it’s built with Python and likely uses PyInstaller, which is frequently flagged as a virus by mistake.
I uploaded it to Jotti, and here are the results:

However, three of the detections are for "Gen:Variant.Yogi.31291"—which is typically a false positive associated with PyInstaller—and two of the remaining three simply flag it as "suspicious." So, it is most likely a false positive.
Still, it’s always best to be cautious; if you have any doubts, it’s better not to run it, or to run it via the Itch app, which includes a sandbox mode that offers a bit of extra protection when playing games.
