When I try to redeem a key for this game, I get this message: The product code you've entered requires ownership of another product before activation. If you are trying to activate an expansion pack or downloadable content, please first activate the original game, then activate this additional content. So which game do I need to own first, in order to be able to redeem this games key?...

puzzle 10 is frozen in a finished state. need to do the puzzle again but it won't reset.

I don't even mind the shapes, but the rotation...

No achievement. thanks.

Finished puzzle 4 twice now without any hints, what now? Space guy is jumping up and down, there is what looks like a rocket thingy with a 'home' button sticking out of the ground. Clicking on it just takes one back to puzzle select screen. I must be missing something obvious, but what? lol Post patch version, have not played pre-patch, so cannot determine if something changed since patch...
