There are so many small details that make sleepwalker such a pleasant play-through! First off, the music and sound design are pretty spot on. The noise when you fall off the level is so appropriate it's hard to even get mad when you fail. This platformer concept is really clever and works super well with the dream narrative you are using. The one problem I came across was the collision detection, where I was able to jump multiple times if I am against a wall, most likely due to a misplacement of a ground check? I couldn't help but to exploit this to clear the levels I played. This is hopefully an easy fix, so overall this game is super successful in achieving a unique platforming experience! Nicely done!
