The third and final chapter in the Hapland series and this one is arguably the best of the bunch. Not only is the game visually stunning, it is also just about the right size and difficulty to enjoy by oneself. A genre defining series from a very talented young artist. It doesn't get any better than this.

Submachine 3 is a point and click game of exploration and puzzle solving created by Mateusz Skutnik. As the intro so cleverly notes, there are no items to collect, no diary to keep, no trash bin to check, and no spoon to, er, bend.
