To coincide with a week-long Steam sale, the enigmatic MirrorMoon EP has expanded its repertoire of planetary structures, adding objects that pay homage to various games, including Kentucky Route Zero and Gone Home. It’s entirely possible that I made a huge mistake when I allowed this one to slip off the frighteningly extensive list of games that I intend to play. I did noodle around with the prototype, which introduced the puzzling concept hinted at in the game’s title, but have only visited the full release a couple of times. It reminds me somewhat of Starseed Pilgrim, in that it lacks guidance or instruction but is constructed around concepts of puzzle and play rather than being a ‘go for a walk’ experience. The game is currently £4.19 through Steam, a 40% discount that firmly plants it in actual EP territory.
