"Core Objective
Control your character to advance along the parkour track. Continuously change your head size to overcome obstacles, deal with enemies, and ultimately defeat the red Boss in a head-to-head collision.

Basic Rules & Controls

Grow & Shrink: Eat blue orbs that match your body color to grow your head. Eat red orbs to shrink it. Your head size is the key attribute for facing challenges and determining victory.

Navigate Obstacles: The track has various obstacles like pillars and balance beams. A larger head might hit high obstacles more easily, while a smaller head could slip through narrow gaps. Adjust your size flexibly based on the situation.

Face Enemies:

You will encounter red minions on the path. Use your current head size to collide with them (usually requiring sufficient size to defeat them).

Finally, you will confront a red Boss. The showdown works like this: when both are close, rapidly tap the screen to initiate a ""head-to-head collision."" The side with the larger head upon impact wins the clash."
