82-0 is a very easy level, created by Castaway.
Walkthroughs:
Method 1 (speed)
For a speed completion, you need to jump to the left wall, get the top few trapdoor switches hidden under the gold, wall-jump back top the tile platform, then right to the door.
Method 2 (gold)
For an all-gold completion, you should jump to the left wall, slide down to the bottom, then go up the "stairs" created by the trapdoors to the exit. For a highscore run, you are required to do corner-jumps up the trapdoors in order to get to the exit fast enough.
