You are a 1970s cosmonaut aboard a scientific research station in orbit. Mission control is on the radio. Your instructions are clear. The tasks themselves are reasonable. The only complication is that without gravity, every single thing you touch immediately becomes a problem.

Heavenly Bodies is a physics puzzle game built around a single brilliant idea: each of the player's thumbsticks controls one of the cosmonaut's arms independently, in full physical simulation. Pushing off a surface sends the cosmonaut drifting. Grabbing a handhold arrests the drift but changes the orientation. Every movement has a consequence, and every consequence must be managed with the same two awkward arms that caused it. Nine scenarios — assembling a space telescope, maintaining solar arrays, tending cosmic botanical research — each introduce new environments and mechanical challenges. The retro 1970s aesthetic draws directly from archival space photography and technical illustration, giving every scene the quality of a historical document about a programme that went slightly sideways. Local co-op puts two cosmonauts into the same chaos simultaneously. The Cleanup DLC adds a semi-open level split across seven in-game days, introducing new tools including magnetic attractors and drills, and runs three to five hours.

Key Features: • Dual-thumbstick arm control: each stick is one arm in full physical simulation • Nine scenarios across a 1970s retro space station aesthetic • 1–2 player local co-op • Cleanup DLC (July 2024): semi-open 7-day level
