I'm really torn with this game. The game itself is great. But it has huge flaws. One can't report the flaws, because their website doesn't work. 1st: the ads break the cardinal rule: never require more than one click to dismiss. 2nd: there's no way to spend the reward tokens. They seem to have fixed the 3rd problem. So I'll add a small one: give us a back button, so we can get to the main menu without having to kill the game.

There are too many ads. A triple layer after every level. But i liked the game so i purchased the ad free ad on around level 125. But it didn't work. Ads kept coming. The game says the ad-free ad on is owned, but doesn't work. I tried uninstalling and reinstalled. I lost all the levels. There is no way to save progress. Not starting over. Requested a refund.

It's always a nuisance when these challenging puzzle games come out and the advertisement is so fun to play but then you get down to the actual game and level one is like... can you turn a button on and off? Good job. Here's an advertisement. It's a waste of everyone's time. You have to play through like 30 levels before it even starts to get good. I just immediately uninstalled.
