This game is safe to download, i run deeper-club on 2 PC's and a Steam Deck, all anti-virus used show no virus.
Make sure you download the game through itch.io and NOT through a third party.
Any claim this game is infected is very clearly false information.
Many anti-virus websites are unreliable as they very often show false positives usually because they refuse to decompress Zip/Rar/tz files.
You could Zip up a Picture of a cute kitten and web-scanners would still complain, theyre terrible antivirus scanners and cant be trusted or be honest with users.
