Curious, I was pondering if this game is in some way linked to I.Q. testing. I completed the game in one sitting which amounted to under an hour. My I.Q. test results were within the populations one percentile with a score of 148. Just using this stat for a person to person comparative purpose.
As far as the game is concerned, the graphics are decent on my late 2014 Macbook Pro Retina 2.8GHz Processor w/16GB of RAM, 512GB SSD, and Dual Graphics Cards (Iris Pro & NVIDIA GT 750M). This game does not push system resources as others have stated. The fans never engage while running the program. It is however, soothing as others have posted. Would love to have more levels or have more difficult levels. Definitely a 5 Star game. I would highly recommend it to anyone interested in a tranquilizing serene expereince.
