4 stars: Ability to change appearance of cars to previous star levels after maxing out. To make the game more interesting, background buildings could be breakable, and more driving around obstacles instead of a short straight path. Possibly miniature monsters that can be driven through, too.
4 stars: a fun game to play. it plays just as advertised, decent graphics, decent sound fx, win for free, imaginative levels, good car control, an all-around solid game. the only downside is that by closing some of the ads, it takes you out of the game and into Google Play instead of taking you back to the game. good news is closing most of the ads does take you back to the game so two out of three ads take you back to the game.
3 stars: its fun...gets repetitive. could use more frequent updates. also would be really nice to watch the monster crumble after you defeat it instead of going right to the win menu that covers it all up. it's like the whole point of the game and you hide the best part. would give more stars with some improvements.
