Pretty damn fun game. Purchased.
Levels get played differently as you collect all the coins from each group (pink, purple, black). Collecting a set gives you 2 tickets to use in Rallys. Unlocking other characters to use in each level is also pretty neat since all the characters have their own perks.
The game is meant to be played with one hand. not having to jump over small enemies just keeps the pace fluid. you earn more coins by doing flashy moves as you automatically hurdle them or by linking squashing enemies together.
