I just watched Bubble on netflix & I thought it was really really good! It's freerunning kind of, really well animated, and cute. I read MC as autistic, too, and I was moved by the representation.
Also -- Sonny Boy, fantastic. I love surrealist / absurdist stuff. In the absurdist vein -- Tatami Galaxy and Night is Short, Walk On Girl (based on mangas by the same author) are both super fun.
