I scanned it in total virus and it found Trojan.Heur!.02252823.
I'm not sure why they made it into a single .exe file but i played the game and it's not suspicious at all.
The EXE file is created by compiling the Godot Engine with Embedded PCK - there are reports of Godot games being flagged as false positive in virus scanners. We assure you we did not develop a virus.
