Mechacraft.io is a building sandbox about making things that move. You place blocks, wheels and engines to put together cars and contraptions, wire them up with logic gates, then climb in and drive to see whether the design actually works.
There is no fixed goal. The fun is in testing an idea, watching it fall apart, and trying again with a better one. The world is shared with other players, so you will see their creations rolling around too.
A good pick if you enjoy tinkering more than racing.
