In addition to the 2 second timer, PQ3 did another thing that's really cool with the gameplay... you can move gems diagonally 🤯 Combine that with the 2 seconds you get to move gems around, and you got a pretty fun game. However game is designed around buying micro transactions for upgrades and chests. And there are way TOO MANY things to upgrade. It's worth it to dl and try it out just to see all the wasted potential.
