This was rated as a comedy? I saw no jokes in this at all. This was still great. My favorite part is how it expands on the world Salad Fingers lives in. The problem is that Salad Fingers is an unreliable narrator. It makes you wonder if he killed that guy instead.
Was that heavily implied? Maybe this great war was what made this world a wasteland. It mutated Salad Fingers into a green monster. His "brother" appears to be a normal human. Everyone was normal before.
