Overview
RESPAWN is a two-player platformer puzzle game with a Cthulhu-style flesh-world theme. You play as a transformable, size-shifting meatball, collaborating with a partner to navigate crises and ultimately escape from inside a giant.
Play it: itch.io

Core Mechanics
Size transfer: the two characters are connected by an umbilical tether; pressing space transfers fat between them, changing their mass distribution and size:
- Large: high mass — can smash rocks and press gravity buttons, but risks failing by hitting the mass cap
- Medium: balanced — can jump and press buttons using gravity
- Small: light — strong jumps, fits through narrow gaps, and can be blown by fans
Transferred fat chunks have collision detection and can trigger mechanisms in the environment. Tether mechanic: crouching fixes the rope length so players can swing to the right position; if the two players drift too far apart, the rope snaps and the game ends.

Props & Mechanism System
Gravity buttons (large size only), fat-collision buttons and trapdoors (activated by fat chunks in transit), crushable walls (large size only), size-check end gates (both players must enter at the required size), secretors (produce fat chunks when a player is detected below), and fans (blow lightweight characters).
Level Design
- Tutorial level: players learn to transfer fat and grow large enough to press buttons — mastering the tether fixation mechanic, then meeting the activated pedal and collide button
- Advanced training: introduces new mechanics while reinforcing Level 1 — collide button advanced training, then combined collide + gravity button challenges


Iteration
- v0.3: just a concept — two players who can change size → added a bond between them as a constraint, enabling size transfer
- v1.1: some mechanism placements made co-op too hard → added press-down and jump mechanics, fixing placement issues and making play more engaging
- v2.0: scene transitions weren't seamless and art style was inconsistent → added walls for cohesive transitions
- v3.1: players reported low immersion, too casual → added a sound system and background music for a tenser, more thrilling horror atmosphere
Project Management
SCM version control and documentation on Feishu.

Results
- Completed and shipped a playable build within the GMTK 2024 jam window
