An absolute classic. Not the first of it's kind in the genre of variety puzzles, but this one definitely does it well. It's got its own flavor with each stage being like a miniature escape room. Definitely worth a play. I came here to review the 2nd game, but that appears to be missing from NG. In fact, all of the mainline sequels are missing which is a shame.
Go give it a play over on Flashpoint =)
