I played the game to the end on the easiest setting and never saw a roller. A roller is like a yellow machine that would roll pavement in real life. There are two roller cheeves one for destroying one and one for dying from one. I restarted the game on the hardest difficulty and picked stage 7. If you beat 7-1 without dying there is a roller or two on level 7-2. Destroy it then reload and let it kill you for the two roller cheeves if you need them and didnt play on harder difficulty in the first place. According to Har Miggido there is a roller on 5-1, thanks for the input guys.
