Nucleon

Nucleon

v0.1 prototype — a browser falling-sand lab about abundant elements, binding energy (⚡), research, and discoverable chemistry. Runs entirely in the browser with WebGPU (WGSL compute + canvas).

Play

Click inside the game once so audio can start.

Requirements

WebGPU

Browsers: Chrome / Edge 113+, Firefox 125+ (WebGPU enabled)

Not supported: Safari (no WebGPU yet); most mobile browsers

Input: Mouse + keyboard recommended

Storage: `localStorage` save in this browser only

Controls

Step (below lab) :Advance one chemistry tick

Space: Pause / resume live sim (after Live simulation research)

Pause: Same as Space

[ / ] Brush size down / up

Mouse:  Paint, heat, cool, erase, pressure tools on the grid

Header: Mute, SFX/music volume, music track (‹ ›)

Save / Clear: Left panel — manual save; clear wipes all progress

Progression (short):

• Step the lab to form bonds and reactions; earn ⚡ from chemistry and codex entries.
• Finish the intro Synthesis quiz to fund your first paints.
• Research expands the palette, tools, lab size, brush width, and sim speed.
• Codex tracks discoveries (H₂, water, acids, synthesis gases, milestones).
• 17 paintable elements, 26 codex entries, procedural ambient tracks (including a piece driven by OEIS A005589).
