Rain World is a great game, but holy cow is it frustrating. And like that's the thing, that's how good the game is; you'll want to play despite the frustration. You're a small, awkward creature. You will stumble and fall around precarious heights, horrific monsters, and more. See some generally bizzare shit. There are going to be unfair situations on account of all the scary stuff out there and how small you are. But if you persevere, if you're wily and nimble, and lucky, there's something really special beneath all the grime.
