Wonderful soundtrack, genuinely recommend getting that alone if you don't want to spend 2 hours on a barebones platformer.
I'd have preferred an animated short for this myself but the game is fine and well worth the painting and music.
Give this to a young kid tho, and it might be one of those things that stays with you your entire life. The advantage of "barebones" is 5 or 6 is probably plenty old to successfully play this.
