Sorry about that, and thanks for letting me know! The game is safe and doesn’t contain any virus. This sometimes happens because the game is a new or unsigned executable, and some antiviruses mistakenly flag unknown files as a threat. I’m working on improving this to avoid future issues. If you’d like to try again, you can restore the file from quarantine or whitelist the game in your antivirus. Sorry for the inconvenience, and thanks for your interest in the game!
