MOBILE GAME OF THE YEAR. Stuff Gadget Awards 2020. This is a stylish and smart take on a now-established genre, and from the second you hear a distant phone ringing, realize you spotted one earlier and frantically scroll back up the screen to answer it, you’ll be smitten. IGN An "Escape Book" that is sure to delight fans of the genre. Engaging, interactive, and with lots of narrative details that will make you spend several hours on your screen. 8/10 BEST TEXT-BASED GAME. PocketGamer. Unmemory is the best text-based game I have played to date. It can be read as a storybook or played as a game. BEST MOBILE GAMES OF 2020. Metro. Dropping you straight into the action, Unmemory’s captivating blend of puzzles and mystery uses every aspect of your phone, from touch to motion to sound and visuals, making it – ironically – a singularly memorable experience.  8/10 BEST iPad GAMES 2020. Tech Radar. It’s rare to see truly fresh games on iPad, but unmemory manages to thrill and intrigue in equal measure, doing clever things with narratives, adventures, and puzzling. THE TEN BEST MOBILE GAMES 2020. Der Standard. "Unmemory" has less to do with the rather dusty "interactive fiction" than with clever puzzle games like "Device 6" or even the logic puzzle "Return of the Obra Dinn". Exciting and extremely stylish.
