From the menu, go right until you get to the ''20.000 lums under the sea'' painting. Now, go to the 3rd painting on you're right (4th if you count the door aswell).
From the beggining, i chose the left side first cause between the right and the left ''door'', the left one is harder. After both buttons were pressed and the lasers guarding the central door were disabled, the tricky part beggins.
Keep in mind that you don't have to rush trough this section since the laser traps are pretty easy but they can be very frustrating if you hurry and make a wrong jump or think that you have time to make a pass by one laser. I also made a video using the game dvr and i was rushing trough the level to be sure that my gameplay of this level doesn't get bigger than 5 min, which is the time limit of a video record at this date (hopefully, in a future dashboard update, the limit will be raised to 30 min) and I got extremely lucky at the end. To make sure you don't get touced by the last laser, after jumping from the first ring to the second one, press
and you should be safe since none of the lasers can touch you under the last ring.
And after that, ACHIEVEMENT UNLOCKED.
