Not right!

Game is good BUT cannot go on unless you buy keys.. Can't even go back if you want to better your score on one of the games

Let us earn keys!

There should be a way to get levels without keys. Like watch an ad to double the amount of games your keys buy. Or, if you beat a timer you can get bonus levels.

Forced to pay if you want to move on

Unlike other games, number knot for iOS gives you a little taste before it locks you out from moving ahead unless you buy keys. My daughter clued me into this game and she has it on her Samsung. The android version allows you to solve puzzles and earn keys to move ahead. I get that some revenue needs to be generated but it’s strange that they treat the two platforms differently. I give it three stars because the game itself is great. Makes you think and work out the solutions. If I could still be playing without paying I would have given it five stars.
