After getting a Mac Mini of my own and a whole lot of messing around, I have finally released a Mac build of Moeblob Adventure. You can download it from Gamejolt or itch.io. Hopefully it everything went OK and it would explode or something.
By the way, have you looked at Moeblob Adventure Expanded? It's the follow-up to this game; all further development to Moeblob Adventure had been moved to that project.
