Chairfighter

A 2D action platformer / mini-metroidvania where a basic chair defeats boss furniture and unlocks chair transformations — each opening new routes through an interconnected world. The furniture went to war. Only one chair can end it.

The arc

Workshop hub → The Lounge (Recliner Baron → Armchair + Recliner) → The Office Complex (Swivel Executive → Office Chair + Bar Stool) → The Storage Closet (Steel Folder → Folding Chair + High Chair) → The Parlor (Granny Tremor → Rocking Chair + Spring Stool) → The Throne Room's eight-form gauntlet (The Upholstered King → credits).

The basic chair starts the run; each of the four guardians awards a pair, for eight earned forms before the final boss. Every earned form has a special verb and a combat identity, and the finale checks all eight in reward order. Casual difficulty: checkpoints heal, respawns keep progress, bosses retain most damage between attempts.

Earned form	Chair power
Armchair	Grapple gold hooks
Recliner	Brace and counter
Office Chair	Dash through cracked barriers
