Light Physics Sandbox is a pixel-art puzzle game about making light useful. Move coloured blocks through compact physics scenes, combine RGB light, and deliver the right colour to every flag.
Light is the rule set
Each block has an RGB mask: it can only be moved when the light reaching it contains a matching channel. White light unlocks every colour, while coloured light turns each arrangement into a small problem of filtering, routing and timing.
Build paths, not just solutions
Prisms split white light, dichroic filters pass selected channels, and colour gates turn light state into level geometry. Blocks carry colour through the scene, so a route that looks correct may still fail until its light is right.
Sandbox and presentation
An in-game editor can place lights, blocks, walls, gates, flags and optical objects, then save a scene as JSON. The project uses Godot 4.5 and GDScript, combining PointLight2D, particles, collision-driven movement and a pixel-font interface with responsive audio settings.
