Starpit.io

A real-time multiplayer .io game where you grow from a brown dwarf into a primordial black hole, devouring rivals under real astrophysics — inverse-square gravity, slingshots, Hawking radiation, and spaghettification included. Inspiration: I love .io games and I love astrophysics — this is what happens when you mash them together. Every mechanic (gravity, slingshots, tidal stripping, black-hole collapse) is based on actual physics instead of scripted gameplay.
