Heavenly Bodies turns spaceflight into a hands-on struggle with inertia. You guide a cosmonaut through a scientific research station, where gravity’s absence makes every movement and object difficult to manage. The premise is practical rather than combat-focused: mission control is available by radio, while the astronaut must use careful movement and judgment to carry out duties in orbit.
Its defining mechanic is limb-by-limb control. The left and right thumbsticks operate the cosmonaut’s arms, which players use to push, pull and clamber through physically simulated scenarios. Those controls underpin tasks such as assembling space telescopes, tending delicate solar arrays and researching cosmic botany. Machinery and vehicles are also objects to manipulate, so progress depends on coordinating the astronaut’s body with the equipment rather than simply moving through a conventional platforming route. A controller is recommended; keyboard and mouse are supported, but are not presented as the intended way to play.
The game supports solo play and local cooperative play, with missions available to tackle alone or with a friend; Steam Remote Play Together is also listed. Its stylised 1970s look, influenced by archival space photography and technical illustration, reinforces the carefully engineered, research-station setting.
