Thank you very much! Somebody else mentioned Queendomino, too, I was a bit disappointed to find our idea wasn't quite as original as I thought, haha!
I don't think that matters much. You can certainly do something your own here. This is why I was recommending to check them out, so you can see what's been done and what hasn't.
I really like the ever-flowing nature of Concrete Jungle. What I don't like is how you can't really have much of a strategy, because you can only see so many tiles ahead. I don't know if the "random piece selection" takes into account the possibility of solving situations. So you can easily get yourself into a situation where you can't win, and it wasn't because you made a bad decision, you just didn't have enough information.
Just some thoughts on what needs solving around this dilemma if you want a strategic and more satisfying experience.
