A relaxed co-op collect-a-thon testing little beyond completionist routing.

Optimization · Practiced Mastery
A meditative puzzle game about wrapping rope efficiently around 3D objects.
LEGO Pirates of the Caribbean: The Video Game leans Optimization (Practiced Mastery); Zen Bound 2 leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
