click the green flag and let the ground generate. you don't need turbo mode. when it's done, a circle will appear. you can control it with the arrow keys. also, because of random generation, the level may be impossible. If you can't get past a level or you just got plain stuck, just click the flag. press r for a new level (especially if the level is impossible) press space for lolz
