make your way from the start to the dive ball

on your way to double jump, use dive in between jumps for a jump to be prepped.

after collecting the dive ball, go all the way right and go up. try to make it in the pipe after going up.

after the pipe, go up. then after you are shot out, go to the ledge at the left. then go up.

after being shot out hold left to go into the screen transition, then go down into the waterfall. and go left until you reach the wall with the pipe, go into the pipe and continue left into another pipe. go down the waterfall and perform the pipe clip.

when in the pipe go to the middle one on the right and go down to collect the iron ball. go to the right, break the blocks, and then go into the pipe.

after the pipe try to make it down without dying. and go right until you can go up. go up then to the right until you have to go up. try to get into the pipe that's on the right side (the same one as earlier)

make sure you hit the bell on the left side before proceeding to the right.

note: make sure you do not touch any other bells after this one. (until you do the death warp)

go to the breakable blocks, break them and go down.

you will then go to a room where you have to go right, then down again.

keep going down till you get to the split paths room, take the bottom path

then clip into the wall, make it into the double jump room, (if you cannot clip into the wall keep going down and try not to hit any bells) collect double jump and then die.

you will be back at the bell from earlier, go to the right and up onto the ledge at the left. go left after that until you get the option to go up. then head left and start jumping from cloud to cloud.

once you are on top of the cloud closet to the entrance you came from, jump up and head to the right.

climb up the vertical section then head to the left. until you reach the entrance that goes up and has stars. stop the timer as soon as the pipe shows on the screen.

congrats!
