MewnBase is a nice little survival game about a cat astronaut stranded on another planet. It's being developed by one guy (so the updates are slow), but it's worth supporting. There's enough content for the price, but don't expect to get more than about 6-7 hours out of it. The basic game revolves around hunting for resources to build base modules, research newer technology and making surviving easier. For example, you start with small garden patches, can turn them into greenhouses, build a water collector and a water distrubtion system. There's also vehicles, several kinds of power generation, power failure, oxygen etc. Worth trying, but low budget.
