Base After Base - the only thing might be the BG blackout and black blocks.

Can't Let Go - upside down ring-jumping, pink jump pads.(it's used for the last secret coin, so it wasn't completely introduced in ToE).

Clutterfunk - sawblades, mini-cube.

Clubstep - Demon difficulty, disappearing spikes.

ToE2 - invisible saws and blocks, MIni Wave, upside-down UFO (if I recall correctly)

Deadlocked - teleportation portals.

Hexagon Force - slow speed portal, dual mode.
