What drew me to Go To Gold by Timur Nigmetzianov was its very nice graphics. I didn't expect that the puzzles would be even better.
I downloaded this game while it was free for a day, and promptly tweeted about it. Make sure to follow me to not lose these opportunities!
Go To Gold is based on the classic Sokoban puzzle, so it doesn't need many explanations. It has however some aces up its sleeve in terms of originality.
