This is not the developer's fault, but of the game creator tool used.
Clickteam Fusion has a known bug where, when it generates a compressed executable, antivirus programs falsely flag it as malicious. The developers never fixed this and left it like that for years. I used it in the past, but my tests were constantly interrupted by this, so I switched to GDevelop.
It was only much later that I discovered the reason for the false alarms, but I am no longer interested in returning to Fusion.
