Ah, thanks bene. Sorry for the scare, I don't download many games from Itch, but this was the first time I got a threat warning. I looked up the name of the threat and it does appear to be a false positive:
"Bitdefender's detection of "Gen.Varient.Ulise.439460" is likely a false positive, a common issue with antivirus programs flagging new or unsigned executable files, especially indies or personal projects, as threats. This happens because antivirus software often uses heuristic or generic pattern detection to identify malware, which can mistakenly target legitimate files that do not have an official or paid digital certificate.
Antivirus programs frequently flag Godot executables or embeds (like single EXE with packed .pck files) as suspicious due to their uncommon file structure and behaviors such as manipulating save files, even though the files are clean."
Anyway, glad to see the web build is working now! Looking forward to playing it later :)
