MirrorMoon EP is a game of puzzles and exploration, with a spatial setting in which each planet is assumed as a puzzle. When you start the game, will find themselves ahead of some screens, some buttons and some dials. There is no indication of what to do, or even what each object does. There are no tutorial and the feeling of being completely lost remains long. When you make it to the first planet will use the WASD keys for movement and will quickly find a structure.
