I found yet another (half) jump skip. For this one, wait on the last platform a little bit away from the spike, then hold left and up, clearing the spike as you jump, and avoiding the ceiling, maximising the jump. From here, just keep holding left and up and you'll hit the bread. I have also managed to still hit the roof and make it to the end, by just hitting the very left corner, and this saves time as you just manage to touch the ledge, rather than gliding against a wall, but it could be fairly inconsistent.

Also managed to get Fastest 9 in a run! I am gonna get consistent at this and then submit... Looking at 2:45!

Now obsolete: a bit of thinking, and I've found the optimal way! Check guides or this video:
