Lep world Z – Lep's World Z - Zombie Games Review

This game has been fun and all but I can’t get any of the boost of whatever they are called to work. The different colored blocks (green,blue,red, purple) I have no idea how to get those to work and most of the stars I’m not able to get because I have no way to get to them because I don’t have those blocks
