ok, first of all i do a couple of jumps forward to get me up to speed and to dodge the rock, then fall between the yellow spring and the spikes and jump left over the spikes, then i stopped myself at the monitor and moved right, then i broke the wall and got the speed shoe which helped me to travel faster, then i ran across the little platform and jumped before i got to the second enemy to go onto the next ledge, then i jumped again and landed breifly on that swirly thing, then took another jump onto the bridge underneath the first fish, then took another jump onto the platform with the rings and the life, then i jumped over the life and landed on the platform with the rock, then i jumped over the rock and dashed across the platforms and the checkpoint, then i jumped and landed on the enemy, then i jumped 2 times to land on the crab, then ran across to that pipe thing and sprinted across the checkpoint. Hope this is enough detail, took me about 10 tries
