Manipulating time, space and sound

There are lot of limitations with the sound in LBP.
I am finding it harder and harder to come up with ways to navigate by sound.


I will also explore how the player can manipulate time and space if I can get the sound mechanics done (+ polished) in time.
Below are some examples of manipulating space and time in games.

"Shadow physics"

Uses light and 3D space for your shadow character to man
Uses a character (who is only visible in the shadows) who can manipulate 3D objects, and can use their shadows as platforms to get from A to B.

"Braid"
Game based around the ability to rewind time. For example you need to collect all the puzzle pieces, you fall down a tunnel, but you miss a piece. You can rewind time to when you are dropping, and navigate toward the puzzle piece.
