Perfect little time-killer for so many consecutive late nights of paternity leave. Just wish it had ben up front with me about how many puzzles it had in store for me. Starts out too easy to be worth your time, then hits a sweet spot of monotonous levels requiring straightforward brainwork. And then the end is loaded with some ridiculous guess-and-check nightmares. So really at no point was this, you know, a "fun game," but at least it stayed interesting long after it had worn out its welcome.
