Neurocriaturas

Neurocriaturas is a free simulation game made with AI by @sebastian20, and you can play it right here in your browser.

Neurocriaturas is a living petri dish. Every creature drifting through the dark is driven by its own tiny neural brain — eight senses in, three urges out: turn, swim, breed. Nothing is scripted. Every behavior you see was stumbled upon, kept, and refined by survival.

Feed the dish and watch purposeful hunter lineages bloom. Spill toxins and watch the survivors grow wary. Click any creature to open its mind and watch its brain spark in real time as it decides where to swim next.

Every well-fed creature splits in two, handing its child a slightly mutated copy of its brain. Smarter creatures eat more, dodge better, and live longer — and the dish keeps score, charting average lifespan generation by generation as your population learns what survives.

Your champion minds are remembered between visits. Return, and the dish wakes them up, mutates them, and lets evolution keep running.
