Credits and licenses

Marble Race Game is published by PractJinGame and builds on open-source projects.

Marble Balance Race physics and artwork

PractJinGame created the Sky Carnival artwork and the passive three-seesaw course. It reuses the bundled LittleJS engine and Box2D plugin, with Box2D 2.3.1 by Erin Catto and the box2d.js WebAssembly port by Alon Zakai and contributors under the zlib license. Common interface translations are inherited from the shared race copy. The game source retains NOTICE.txt and the existing engine notices; no new external artwork or fonts are required.

Marble Elevator Race physics and course

This original PractJinGame bucket-lift and downhill course uses LittleJS and its Box2D plugin, with the bundled Box2D 2.3.1 WebAssembly port. Box2D is by Erin Catto; box2d.js is the Emscripten port by Alon Zakai and contributors under the zlib license. Common interface translations are reused from Marble Switchback Race. Engine and license notices are retained in the standalone game.

LittleJS and the original LittleJS Arcade launcher were created by Frank Force (KilledByAPixel). Their MIT license allows reuse with the required copyright and license notice. The repository retains its LICENSE file; using that engine does not imply its author endorses this site.
