Release your finger from the screen to stay small and fast and run past all the giants, or hold your finger on the screen and grow into a giant and fight!
Slide your finger left and right to move, your avatar will auto run, if you are too small you will bounce back off the red green yellow giants, boing like pinball, so you must grow big and punch them all. Boom, knock em all off the platform! Like a Boss.
You will run slower when you are a giant, so get small by letting go if you see a gap and think you can make it to the finish line for victory!
Easy peasy to play, impossible to master.
