Four stars for the engaging gameplay loop that asks you to delay instant gratification and plan several moves ahead and forces you to enact patience and constrain by tricking you with little false chances to have a perfect level even when not having those perfect levels it’s more often than not the easier path to victory. It’s almost mathematically balanced, yet you keep swinging for the home run despite your best interests. One of the few games were the player makes it more punishing by its completitionist tendencies while the game itself is rather forgiving. It’s pretty genius.

One star deducted for at least partially contributing to the persistence of the idiotic I.Q. as a measurement of intelligence myth. I don’t make the rules.
