Yeah, originally it was going to affect vision/hearing (by updating graphics/sound), your speed (by letting you move and shoot faster), your strength (life), a psychic ability (enemy and bullet knock back), and a the ability to rewind time. At the last minute I took out everything interesting because it was working a bit too wonky. The bosses wouldn't rewind properly and the knock back was pretty much doing the same thing as rewind, so it got scraped so that I could rush music and sounds.
