Well.. a late update on this. I got really demotivated when it turned out there was literally no-one playing the Great Orb Project. Well, only a couple of games a day organised by friendchats because it's a requirement for an Achievement Diary or something.
Right now I have no time to work on this. I hope to continue and finish the development during my Christmas break. I will probably need some help from others to actually get a game started. But that should be possible!
