Solo dev builds Spore-like evolution game with Claude, free demo on itch.io

Reddit user Ouvolk detailed Primordium, a Spore-inspired evolution/strategy game built solo alongside Claude. The cell stage demo is free on itch.io, with a Kickstarter page live.
How Claude helped:
- Procedural IK & locomotion: multi-legged inverse kinematics and foot-planting that adapts stride across arbitrary body plans (bipeds to 16-legged crawlers to webbed swimmers)
- Aquatic-stage math: 3D swimming physics, drag, and fin-to-leg beaching transitions
- Tribal possession: swoop from RTS view into any tribe member in third person, with metadata task-stashing so unit AI resumes seamlessly
- Automated headless test suites and fast autoplay bots catching regressions and physics bugs
Gameplay: a new reef-lagoon swimming stage; parts with real physical trade-offs (webbed feet reach deep water, burrowing snouts hide you, stilt legs wade but fall easily); an ecosystem with memory — overhunted prey flee and hold grudges, befriended species warn of predators; volcano events reshape terrain and leave fertile soil generations later.
