This not a bad game at all. It is a mix of platform and cube matching, both of which we've seen before. The Henry Hatsworth bit might be an attempt to cash in on the Professor Layton, period styleadventure...but it's nothing like that.
Takes a wee while to get into, isn't too taxing and quite frankly does exactly what it says on the cover. This is the sort of game that is ideal to pick up, play for 30 minutes, put down, do something else, pick up, play...you know the sort of thing - and it's reasonably priced to boot!
