Playful nature of the game. Mistakes don’t feel wrong, they simply feel exploratory. For example, Stucco can punch a giant mushroom, which bounces back and knocks him out. As a result, the other goblins guffaw at your mishap, but Stucco revives none the worse for wear. And for the most part, you’ll get an idea of who needs to interact with what from these animations, so it never feels like a waste of time to experiment. There are some time-sensitive actions required occasionally, and these could prove troublesome, but such moments are short and can be tried again if necessary. The earlier levels may lull you into a fall sense of confidence with their pass-like-clockwork degree of puzzle solving, but really they’re meant to serve as a simple transition into the extremely difficult levels you’ll encounter later.
