An accessible game where the input device is the player. Built on UCL’s MotionInput, so the controls are gestures rather than a gamepad, which turns out to constrain the terrain, the camera, and the pacing far more than it constrains the input code.

What it does

• Marching Cubes terrain with chunked SDF streaming, custom triplanar shaders, and collider pooling, all GPU-driven.
• Procedural collectibles, first-person controls, and unmanaged-memory hot paths in C# and HLSL compute shaders.
• MotionInput gesture recognition for accessible play, recognised in partnership with the National Autistic Society.

What was interesting

Writing C# that does not allocate. The gesture pipeline and the terrain streamer both run every frame, and the garbage collector is the one thing a player feels immediately, so the hot paths ended up in unmanaged memory, which is a strange place to arrive at from Unity.
