A hospitalized boy and his mother enter the storybook world of Rakuen, where the characters in that world are connected to people in the hospital. World is well designed in a 16-bit sprite style. Good music, with creator being behind the music of To the Moon. Funny moments that poke fun at game tropes. Puzzles and quests to help your friends take the place of combat. Well told story dealing with patients and memories lead to themes of death, illness, loss, and acceptance.

A not dead mother is a major character, that's rare.
