OneMoreStep
An endless climb, built for phones
One More Step is a mobile-first 2D vertical platformer. You guide a small pet up an endless climb around a giant tree, where speed turns into higher jumps and falling off the bottom ends the run.
It is an independent creative engineering project, and a place to test how mechanics, feedback and progression work together when real people play them.
Systems in the game
Momentum movement
Running builds speed, and chained fast jumps climb higher, with wall bounces, coyote time and an earned double jump.
Progression and skills
Two pets share the same physics but have their own signature skills and ultimates, charged by combos and spent with mana.
Content-driven worlds
Worlds, pets and hand-built climbs are data. Floors up to 999 come from a purpose-built World Generator, and everything beyond is generated live.
Touch-first input
Touch handling was hardened through phone playtests, including recovering from finger releases that mobile Safari sometimes drops.
How it is built
Tested as it grows
Unit tests and scripted browser checks run alongside rounds of playtesting on real phones.
Documented decisions
Game design, tuning values and a development decision log are kept as maintained documents.
