When browsing recommended lists and best of lists, Suveh Nux springs up frequently, so I decided to play it.
I can only agree with other reviewers that this is an excellent puzzle-game. Everything works, there's more than one "Aha!"-moment, and there are almost limitless possibilities to experiment, combine stuff and spells and stand in wonder at the results of the latest whim you acted upon.
I loved the brain excercise of solving the logic/language puzzle. The game is a great cerebral A-implies-B problemsolving excercise, with a very big sandbox.
Personally, I like a bit more involvement, the feeling that there's something bigger at stake, but that's just me.
