Steam reviews

What players say

Players overwhelmingly praise its deep, realistic physics sandbox and free price, though a few note a dull feel and occasional performance or update problems.

Many players enjoy the physics simulation, where materials react to heat, pressure and each other in ways that can be built into reactors, circuits, bombs and surprisingly detailed models. Some players call it a free, lightweight sandbox that runs well even on old laptops and phones, and they praise the community saves that others can open and learn from. Several players mention that the wiki helps them learn the elements. The complaints are mostly about the element list, which some feel is missing things such as moving solids, and about performance slowing down when the screen is crowded. A few players report bugs, including a fullscreen problem during multiplayer and an update that broke the game for them. Some players found it boring after a short time or said it lacks goals and is closer to a lab tool than a game.

Who it suits

Suits players who enjoy open-ended physics experiments, building machines and reactions, and anyone who wants a free, lightweight sandbox.

Who should skip it

Players who want clear goals, a story or lots of content should skip it, as should anyone who needs a stable, bug-free experience.

Short vs. long playtime: Players with hundreds of hours mostly praise the open-ended creativity and community creations, while those with a few hours more often mention the limited element list and the slowdown.
