Foam

Embodiment of that sort of “shit just happens”-ness, the vaguely threatening alienation, of being a kid in the world at large. An umbrella fetch quest takes a turn. Become a submarine, a fire, an incomprehensible language of adults. Be an egg, deliver an egg, receive boons from jerks. Become the fucking moon, make some astronomer-wizard's day. Similar to, say, Legend of the Six Rooms in that it's more of a puzzle of discovery where you benefit from taking notes/making maps as you go. Once you know where things are and how to bypass certain obstacles everything slots into place very straightforwardly, but that process of discovery (of figuring out how things work when almost nobody wants to tell you so) is strange and satisfying.
