Eclipse
A movement-platformer where changing realities changes the rules of physics.
A high-speed 2D movement-platformer built around a dual-state world-swapping mechanic, where players alternate between the grounded physics of The Fragment and the weightless Resonance to traverse spectrum-locked environments, fight enemies, and survive a collapsing reality.
Challenge
Global Game Jam 2026 was a hard timebox: prove that a dual-state world could change traversal, combat, and geometry without feeling like a gimmick, and ship a playable vertical slice with a visual identity that could continue after the jam.
Solution
We treated state as the interaction model, not a visual filter. Visage switches the player between The Fragment and Resonance: Fragment is grounded melee against solid debris; Resonance is weightless movement across luminous terrain with sonic pulses. Contrast tells you which rules are in effect. Momentum stays in the player's hands rather than interrupting it. Complexity has to stay readable, because visual clarity is how the dual-state world teaches itself.

Narrative
The world has been bleached of color and meaning, harvested by the Veiled. The player is the Fragmented One. Using Visage, they reveal Resonance — the other state of a collapsing reality — and fight to survive it.

Impact
Eclipse is a playable original IP. It was submitted to Global Game Jam 2026, won the Most Fun Award at CIIT College of Innovation and Integrated Technology for that entry, and continues in development as a Kamiyon Studio original.
Lessons learned
A dual-state mechanic has to change the whole game, not sit on top of it. Validate movement early. Visual clarity is gameplay clarity. Game jams are a legitimate way to prove high-risk concepts.
