The project is very interesting, but as I understand it, the creator is tired of it because they don’t see any success in it — and that’s actually the case. I think the author should find investors or sell the game to more serious parties that have the resources to bring everything they’ve planned to life and to work on the marketing side, because one game isn’t enough!
I think nothing will happen; if we’re going to sue, let’s sue all the games, since every game is a copy of one game or another.
The game’s author did what everyone else does. He didn’t reinvent the wheel; he took the necessary implementations and started making the game. I also make games, and if I see someone doing what I do, I just accept it, and instead of complaining, I try to make it better — that’s what competition is all about. Players get only the best content as a result.
