Questions
Is it really free?
Yes. Gemporium Demo is free right now on Steam, with nothing to pay.
Is this the full game?
No. A demo is a portion of Gemporium Demo — usually the opening section — published so you can try it. It is free permanently, but it is not the complete game.
Where do I claim it?
On the official Steam page. We link straight there — we never host game files or act as a middleman.
