I was completely forgot about spinning, until I saw the technique demonstration, I didn't expect a tip on mid-game, that was nice. I felt like I was too quick max out all upgrades, and the stone mitosis look very satisfying.
Thanks for playing, yeah I kinda regret not adding more upgrades, but at the end when the stones multiply too much the money is not really a problem, and I didn't know how to spice things up, and thought to leave it at that.
