Thanks for letting me know, I've heard someone else say this about an older game I made with this engine. Could you give a bit more info on your OS and such? Perhaps you could try running the game as an administrator or in compatibility mode.
Im using a Windows 10 hp laptop, i've never had this problem wth other games but i also dont know how to run the game as admin. I tried the other settings too and nothing changed.
I just tried one last thing, after this I really don't know anymore :p Could you try re-downloading the "click to run .zip" to test? Would really help me out, thanks!
