You should add some sort of special currency that you get from every 10th material the first time you destroy it or every 10 minutes or something. Just some material that would make players feel like they have a resource that is fairly limited
I enjoyed this game and the scratch game, but the game itself seems very linear and fairly slow. For me it starts to become tedious to build up hpoints to buy nights of hanukkah. It's definitely better/faster than the scratch card game, but I think it still needs a bit more speed, especially since you added another layer.
Thanks for your feedback! I will add more tooltips.
