“A robot without a goal is nothing more than a calculator. So, listen up... Your goal, is to find Earth. Do we have a deal?” - Dr. Lisa, the creator of the robot and who believes that Earth is not just a myth.

“We have a deal… Emeth will find Earth!” - Emeth, the robot.

Someone should lets play this

This game is so good! The graphics are really appealing and the dialogue is full of emotion and personality. Emeth is a lovable character that you fall in love with immediately. I would totally recommend this to everyone! The fame allows you to roam freely and does not have a limit to how much you can use the telescope as does many games. Without restrictions this game is enjoyable and captures my and im sure many others attention.
Also spoilers!!
it tells a of an amazing and crazy story of humans that forgot even earth existed. And now Emeth is in charge of finding earth before humanity perishes. I love this so much and i hope many after me find it just as enjoyable.

Amazing Story and Game!!

I don't write reviews often but this game deserves it. This game has a very engaging story! You feel attached to the characters and you care about them. Although only around 60-90 minutes long, the game has a very complete story with memorable characters, beginning, middle and end and a very clear goal. This game is absolutely amazing and it's a very nice variation from the copy paste games the App Store has to offer like clash of clans and it's clones and Game of War and it's clones. You don't see very many apps that actually have quality games with story and for that you get 5 stars my friends!

S.T.U.N.N.I.N.G !!!!!!!!!!

A complete change of pace , not jut a game, nor just a story, with perfect ambient music and graphics . . . Human (me) cooperates with Emeth the robot to find Earth; Emeth must cooperate with Dr. Lisa's hologram. All three of us need to be successful to save the human race. No shoot-outs, no aliens, no gore, but so engrossing that the first time I got a planet Earth "match" with 70% of identical features, my heart made a leap and I literally held my breath, as if _I_ were the one lost in space..... Very hard to put down, but if you do, you can rest assured it will wait for you . . . An absolute delight of a "game."
