So how long is a single chapter? The game looks intriguing and high in quality and all, but I doubt I'd spend money if this is just about an hour to finish? Also, is a single chapter going to be about $20 or 5 chapters in total is going to be about $20?
Anything you want to ask
Hello, which OS is in question? It seems like some files may be missing - check if your antivirus has maybe removed some files.
Edit: I see now from your other comment that it's macOS Sierra. I will check now if everything is OK in the macOS build.
Did you maybe move the app outside of the folder it was unpacked in? I've been able to reproduce the error when I moved demonheart.app to the desktop.
It seems like there was an issue with file permissions. I re-uploaded them. Please try to download now.
