Maybe just try and have some more content than usual to let players explore, add something visually beyond translating objects around to try and capture people's imaginations, like fluid simulations, physics simulations, dynamic destructibility, more complex animations exported from modeling software, even if their interactions with the player are mostly aesthetic and not mechanical.

Also it's full of golf graphics or something, what is up with this game anyway?
