A sad little diving helmet-faced robot charmed many fans back in 2007 in his game Automaton, but things didn't pan out as the developer expected for making sequels. This new point-and-click adventure doesn't provide plot closure and it's on the short side, but it does provide fans with a last round of puzzle solving and lovely animated cutscenes.
Adventure games are tough to get right: they generally rely on the craftiness of their puzzles and the strength of their story, and balance is key. Hard puzzles are fine, as long as they involve some sort of logic. I don't appreciate the kind of adventure game that has you put masking tape over a mouse hole so it picks up the hair off the mouse, allowing you to use the hair and some glue to make a fake mustache to sneak into the library. What kind of sense does that make?! Who sneaks into a library? It's a public building!
