Astronimo
If your Friday night group needs something to yell at each other about, this physics-based co-op builder delivers genuine chaos across four alien planets, though solo players will find it a hollow experience.

About Astronimo
I want to be straight with you: Astronimo is not the deep contraption sim that the building-focused screenshots imply. What it actually is, once you strip away the space setting, is a couch-and-couch-equivalent party game dressed up in physics-puzzle clothing, and whether that excites or disappoints you is the whole ballgame. Up to four players take the role of stranded Hypergiant Inc. employees who need to explore planetary surfaces, collect resources, and eventually assemble a shuttle to get off the ground. The goal structure is simple enough that anyone can follow it, which is a genuine strength when you have mixed-experience players in the session. The controls work similarly to Human Fall Flat, where each arm is managed with some degree of independence, producing the kind of floppy, unpredictable movement that either reads as hilarious or infuriating depending on your tolerance for intentional jank. Building itself is accessible, snapping parts together to produce vehicles, lifts, and rockets of varying absurdity. The honest limitation here is part depth: players hoping for pistons, logic gates, or the kind of layered engineering you find in Scrap Mechanic or TerraTech will run into a ceiling fairly quickly. What you get instead is fast, low-friction assembly meant to produce laughs, not optimised designs. That is a design choice, not a bug, but it does set a ceiling on long-term engagement for anyone who wants to min-max their way across the solar system. The campaign spans four named planets, Turilla, Acara, Zaroth IV, and Nixnillon, plus four mini-moons, which is a respectable amount of handcrafted content for the genre and price tier. The World Editor and Steam Workshop support give the game a longer tail than the campaign alone would justify. If the community produces decent planet packs, the replay value extends meaningfully. At launch the Workshop was modest, but it exists and functions, which is more than can be said for several games at this price point. Partial controller support is worth flagging: in a game this physically chaotic, an awkward input config can tip frustration into the red, so verify your setup before gathering a full lobby. Solo play is technically supported but structurally thin. The puzzles and pacing assume cooperative friction, so a solo run mostly highlights the parts that do not hold up without social energy. The Steam review sample is small but sits around 82 percent positive, which tracks with what the gameplay suggests: people who bought it knowing what it was enjoyed it, people expecting Scrap Mechanic in space left disappointed. Manage that expectation carefully. This is fundamentally a game for groups who value shared silliness over technical mastery, closer to Overcooked's spirit than Kerbal Space Program's.
