Oh, actually after trying to opening it with the Terminal (`open Feltari.app -e`) and receiving a different error, it worked hah.
Wow, I think this is great! The map felt a bit too big / empty but it's a nice idea and well executed. Congrats!
So did you have to open it via CLI without any other mean to open it?
Yeaaaah the map is the biiiig biggest problem! ^^ But thanks! :)
Yeah, after doing that it just worked!
Alright then! I'll see what I can do to make it runnable without CLI so that it's simpler for "basic" users.
