An observatory, labs and a rocket pad. Claim your pressure suit (helmet, chest, leggings, boots) in white, slate, teal or orange.
Real in-game screenshot
Mars settlement
Sealed rooms and pressure doors on red terraced ground. Launches between Earth and Mars: a countdown, then a short jump in a burst of flame. The rocket on each pad is scenery; you don't fly it.

The J menus don't pause the game. Press Esc to pause.
This is a test build from a small fan studio: few people have played it yet. Found a bug? Tell us on the feedback page.

For parents

The labs teach simple science ideas (measuring, recording results, what is left over after a recipe) with in-game experiments and a field guide. No account on our site, no ads, no chat added by the pack, no tracking cookies. Questions: contact@bebemonsieur.com.

Playing together safely: in COMET DOCK you play solo, so by default nobody else joins your child's world. Playing with a friend on your home network (LAN) is in testing and switches on only if it passes; we never run a public server. Microsoft Family Safety can allow or block multiplayer, and chat can be switched off in Options → Chat Settings.
