Liking this game, except for time-limited levels. Those are clearly money grabs because you either have to pay for additional boosters or lose over and over until you get bored. If it gets any worse I will have to dump the game. I put up with ads because I know that's how game Devs make money for keeping things running, but I don't have any patience for no win unless you pay games. Either lengthen the time durations or dispense with the ads that autoplay when the player hasn't clicked to see it.
