It's a cool concept, makes for a fun demo. Also a pleasant surprise to see shanghai gold in there, so thanks for that. I like that there's heaps of random events that keeps interest up. Would maybe like to see some crazier upgrades that can essentially break the game, like humongous coins of 1000% speed coin pusher. Performance and physics simulation could do with some work. In terms of potential, I don't think it would really work as a full retail game, but nothing wrong with having a fun demo to flex your skills. Was fun to play!
