In short it's a great story driven experience with casual gameplay elements. Platforming & Puzzles are not too difficult but can be frustrating due to the performance issues. Demanding areas saw my fps drop to 10-15. Graphics are beautiful though and the moon looks breathtaking. It is a full journey with start middle and end all tied together nicely. I gave it 4/5 purely because of the performance issues, particularly in the last quarter of the game. Parts of the game had to be replayed by myself as the fps drops were making it impossible. This is a shame in an other wise fantastic game. I'd definately recommend it pending you're prepared for some technincal issues. I wouldn't advise playing it with anything less than a good dedicated graphics card.
