This video shows the NEW Mine Door Skip using the freak pushback. It can save over 1 minute in comparison with Minecart skip (previous best strat).

Here's the same strat applied to the Orbs category. It can save at least 2 shockwave cycles.

MDS Step Off (guide):

1. Send elevator up and immediately go to the right;
2. Turn LEFT and get picked up by the freaks;
3. Tap JUMP, tap LEFT then tap JUMP again (to cancel the step off); [ tapping jump before any other input is necessary only in the elevator, otherwise you drop straight down ]
4. Hold RIGHT to step off towards the door; [ step 3 and 4 are necessary to make sure you'll get pushed towards the foreground ]
5. Wait for the boy to reach the floor, then tap LEFT and get picked up;
6. Tap JUMP, and hold RIGHT;

• Repeat step 5 and 6 until the elevator stop;
• Repeat step 5 and 6 without the JUMP input, all the way to the pressure plate;

7. On the pressure plate, alternate between left and right step offs;
8. When you're far enough into the foreground, step off towards the door;
9. Continue the RIGHT step offs into the door until you pass it.
