Gridmax is in Early Access but very much playable now. It is a survival and building game with some colony and management features. Coded in C++ with SDL2 library so it runs pretty fast and can do a lot of fancy stuff :) The most interesting feature is the ORDERS system. After you get settled in with survival you can summon gridlings to help you continue building and mining. You can establish jobs such as "Gather 5 wood", "Make 5 Doors", "Build Doors here and here", and they will all get to work until the job queue is complete.
