I consider the gameplay to be good, some puzzles could use a little more info but overall good puzzle design. The reason for my negative review is how piss poor the optimization for such a simple game is.... no matter what graphical settings I chose I consistently had extreme frame drops/stutters. The game was nearly unplayable due to the issues and I wouldn't recommend playing the game unless you just really want to finish the series.

Edit: After completing the game I now recommend the game even less than before, the performance was even worse in some areas and a handful of puzzles had good ideas but overall had poor execution making them very difficult to solve without extra insight... Overall still don't recommend the game unless you just need to finish the series
