Pen Slime is a 100% pen-rendered soft-body slime. No costumes: everything you see is drawn with the Pen extension every frame. HOW IT WORKS - Verlet integration + position-based dynamics (16 points, 2 substeps per frame) - Pressure: area constraint from the shoelace formula, gradient = 1/2 (y_next - y_prev, x_prev - x_next) - Shape matching: best-fit rotation = atan2(sum r x d, sum r . d) keeps it round - Smooth Catmull-Rom spline skin with layered glossy shading - Terrain: sine waves + a Gaussian basin, with slope normals and friction - Pokes: Gaussian-weighted impulse e^(-r^2 / 2 sigma^2) - All 22 sound effects synthesized from math (no recordings) CREDITS Game by @e5b Music: Frutiger Aero Skyline Remixes welcome; give credit!
