Not really my kind of game, and I'm not entirely sure it honours the theme, though it is clearly includes elements of shapes. I rate it 3/5 stars for "adherence".
Other than that, my goodness what a complete game! Very cohesive experience, and a lovely UI. A story, combat and exploration, this is very comprehensive.
One small gripe, it is a bit of an audio bomb, I had to turn system volume WAY down to 2 out of 100.
Anyway, very cool! Very complete!
