It was good until I purchased no adds, 1rst I can't upgrade my power without closing the game and upgrading your power before I start melting snow. 2cnd I supposedly won the 1 million coins only for it to put me in the negative so now I'm stuck on a level trying getting to get back into the positive, 3rd every time you advance to another level you have to upgrade your power, and 4th in order to sleep you have to watch adds
