Being Zachtronics' last (and final) game I was expecting some great or very complicated puzzle adventure but thankfully that wasn't it. Why do I say thankfully? Because what they've left is really neat and that is exactly what you should expect when playing a game of theirs.
It's a collection of games so not all of them might be to your liking but they're there for you and you can play them to your heart's desire, or not. One game in particular became really addictive and kept me stuck to the screen for the whole game but apart from that they're all solid puzzles. Definitely a great goodbye
