...empty... it feels so incredibly empty...
Island is there just to adhere to theme, and everything else conveys little meaning or emotion of its own.
It has such a great parody, creepiness and genre subversion potentials you can almost smell it, but it is not used, and mechanics doesn't really cover for the loss.
If you want to know how to subvert game genres, look up Frog Fractions which is dusguised as a children game. Frog Fractions 2, which is disguised as Glittermitten grove (a management game about fairies) is even more mindblowing.
