Amazing but short

Wow I can't say enough. Beautiful graphics and touching story. But the ending is abrupt as hell and doesn't really wrap up what happens at the end. Where did makoto and the doctor go to? What happens to Emeth and Lisa after the ending? Also I played the demo and loved it so I spent the $10 for everything. I can't say I'm not a bit disappointed at the ending and the lack of expansion from all the add ons.

How do I get the final secret for Emeth's armor? I found all of the clues and then got the short cutscene of the ancient civilization but there is still one more thing left to do and I can't find it. I paid $10 for this, please let me know how to get the last secret. It would make the disappointment from the ending feel slightly better.

It seems that from others reviews of this game and the sequel, that you guys do great at everything but the ending of games. Hopefully you'll put out some more updates for this game sometime in the future.

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!
