Fancy Stairs vs Red Ball

红球需要爬上楼梯看中的真快。

Fancy stairs sink down bottom of screen and red ball can't touch the bottom of the screen. So red ball need to climb the stairs up quickly enough to hurry to the next step and it's not very easy task to climb the stairs when you have so little of time. Fancy stairs sinking faster and faster, so you need to be faster too.
