A good quality game of its type:
The Artifex Mundi engine is very good, puzzles all good with a lot of variation. Not my favourite Artifex Mundi game and I have played all of their games that are currently on Steam, but definitely worth playing by any fan of the genre.
I should mention that apart from the game engine, which is very slick and for instance auto zooms when you need it to, it has the standard map feature which is present in all but one (the oldest) Artifex Mundi game currently on Steam which allows fast travel by clicking on the location in the map screen.
The artwork is the usual high standard I come to expect from Artifex Mundi.
The games main feature which sets it apart from other Artifex Mundi games it involves time travel, such that you have travel to the past, change something and then return to the present, or to a later time to advance the plot of the game.
So in closing I would recommend the game, as I said not my favourite, but well worth playing and playing this game did cause me to purchase and play all of the other Artifex Mundi games on Steam which is a recommendation in itself.
