15-4 IL 435 (1m 5s) WR

This run improves the previous tied record by 5s.
RTA time: 1m 15s 520ms (prev. 1m 21s 167ms by me)
In-game-time (IGT) time save is entirely from the earlier skip at 0:12.
I also saved RTA time from skipping the 2nd checkpoint without slow down which also makes the last pipe transition faster.
let's go over this new skip in more detail.
The premise is that we can do the normal skip 5s earlier by damage boosting from the first set of spikes. However, this means the damage-boost now doesn't last long enough for the skip to work. This is solved by slowing down to manipulate both cannons to shoot such that we can bounce on them both to avoid needing to damage-boost on the munchers.
This skip is a bit tricky, but it is consistent. To do this you need to; Hold left about 1.5 blocks before the second set of spikes, as soon as you land simultaneously do a very small jump (I spin-jump) and switch to holding right, keep holding right and do a full duckjump as late as possible, then if set up correctly all you have to do is keep holding jump and you'll bounce and land on the pipe.
For the cannonball bounces to work you must be ducking and holding jump. (note: I release jump once I hit the ceiling to get the CP but you might not make it when doing this)
IL count: 100/100
