There's more apps than you can shake a stick at, and most of them are a swindle. Just kidding, I haven't even checked that many apps out. But considering, well, you know, the market, which consists of people pumping out as many clones as they can... Well...

Anyway, I still have some hope about the game idea. But beyond the grammatical complications, I still don't have any good idea as to what it could be about. Took a shower with the specific intention to figure that out (if that makes any sense), only got so far as it could be about searching for a person (in a foreign land, I suppose). And also, at the start you get told an absurdly complicated word (which is most of them in German :-)) and have to eventually figure out what and why. Except the problem with this idea is that, depending on your level, it might not be complicated enough... or instead, too complicated... But it's kind of interesting. A mystery...

Oh, about the lyrics. Nothing really wrong with the translation, except I don't see why the word order has to be changed in the third line. It sounds just as fine in English. That is - "It is the brightest star of all".
