Solo: Islands of the Heart is one of the most unique games I’ve played to date. A hybrid between a box puzzle game and a love/relationship personality test, developer Merge Games has done an amazing job to make the collaboration feel very natural. Everything about this game seems to just fit, even though some elements are purely cosmetic or explained in great detail. Two small issues I do have with the game is the controls for the camera and the user interface. Neither is a deal-breaker, but a little bit of tweaking from the developer and a patch could quite easily improve these minor issues.
