This game is currently in Early Access. Expect frequent updates. Please join us on Discord to report bugs or provide other feedback! Awaken alone aboard a damaged ship, drifting near a forming star. Your survival depends on learning how to collect, separate, and combine the fundamental building blocks of matter. Isotonaut is a science-driven space simulation focused on discovery, systems, and progression. Gather isotopes from stellar winds and frozen ice belts, refine them through interactive separation processes, and synthesize new nuclear configurations aboard an orbital station. There are no enemies, no timers forcing constant attention — only curiosity, careful management, and the quiet hum of machines running in the background. Features: - Explore space environments to gather raw isotopic material - Separate and catalog isotopes using puzzle-inspired mechanics - Fuse isotopes to discover new structures and expand your registry - Upgrade your ship and synthesis chambers as systems unlock - Uncover fragments of your ship’s lost memory through scientific progress - Atmospheric soundtrack designed for calm, focused play Isotonaut is designed to be played at your own pace. Check in, make discoveries, let systems run, and return when you’re ready to take the next step. Whether you enjoy space, science, or thoughtful simulation games, Isotonaut invites you to explore what happens when curiosity becomes your only guide.
