Navigate across the elevators to collect stars.
Tap on the right side to jump right, tap on the left side to go left. But be warned, you only get to backup (go left) so many times, making it more difficult. Collect backup stars to gain more steps backward. Yellow stars are worth one point, but blue are worth two and red are worth three. More rare are suns, which are worth 10.
Avoid hammers, which will remove a point and cause you to start over. Fire does the same thing. Check if theres fire below, if not, then you can jump down and loop around to the top.
Negative comments in the reviews will be used to make the game better. Thats not a path to winning.
