Thanks, really glad you liked it. For now, I'll focus on tweaking and updating the current version. But yes, I'm planning to add more maps in the future, including underwater salvage and a car junkyard.
I don't know whether that makes things better or worse, but the balancing is all on me. The thumbnail is also just a manually arranged and rendered scene. So I can still make bad games all by myself, just like in the good old days before AI.
