MewnBase invites the main character to take control of cats who have gone on a space journey through a two-dimensional world. The passage involves spending all the time searching and exploring. Cats descend to the surface of the Moon, and they do not have any tools. And only after descent they get the opportunity to create objects. First you need to start building a lunar base, which will be temporary. It doesn't take very long. But it takes a long time to equip it. A large number of different modules are available in the game. Each of them is needed for a certain type of function. Modules must be created and integrated into the space base system.

In MewnBase you can find valuable items scattered in various places. After finding and using them, the base is improved. In addition, you can achieve the discovery of new engineering schemes. It is especially important for the user to monitor the extraction of resources and their use. There are many such resources – solar energy, minerals, water, air. You need to monitor their level all the time. So, if the oxygen runs out, the cat will die instantly. In the game world there is a change in weather conditions and time of day. There are periods when thunderstorms, hurricanes and other disasters strike the Moon. To protect themselves from bad weather, astronaut cats need to be hermetically sealed at the base and charge the generators. This will help you not get lost in the dark. You can even create vehicles on the territory of the base. But for this the base needs to be improved. Means of transportation are extremely important so that resources can be found faster.
