Decent game ruined by the difficulty

Most of the levels, especially level 20 are impossible to beat, at least not without the help of boosters, which unfortunately, you have to pay for. We shouldnt have to pay for anything in order to progress through the game. Tone down the difficult or at least allow us to somehow pick up boosters during the level. The game can be fun, but the difficult is just too ridiculous.
