Controls

• A — left hand reaches up.
• Z — left hand drops down (also dodges left-side pots).
• K — right hand reaches up.
• M — right hand drops down (also dodges right-side pots).
• Esc — pause / quit.
• F1 floor, F2 score, F3 lives, F4 hand status.

Climbing

• Both hands grip windows. Alternate hands to climb: A, then K, then A again, and so on.
• Hands cannot be more than one floor apart. The lower hand must catch up before the higher one can move further.
• Each ear plays the corresponding hand's grip tone. Pitch rises with altitude.

Hazards

• Falling pots whistle from above on the left or the right. Press the matching DOWN key (Z or M) to dodge.
• Windows can close on you. A creak warns you a second before. Move that hand quickly or you fall.
• High floors hold a gorilla. Its roar throbs in the centre. When it swipes (whoosh), drop both hands at once.
