Doing a single-session clear of this had been on my "things I want to do at some point"-list for quite a while and I finally did it :)
(and with a non-awful time as well, so I can now pretend I speedran a kaizo hack....)

One thing I like about SMW is how it is possible to create stupidly precise setups without placing down a lot of stuff.
These are 71 blocks, 16 sprites, and 7 forced pauses :)

Another room from Flying High Again by Noise.
I liked this room, yoshi flight is something I haven't really TASed before and the beginning and ending setup are cute mini-glitch puzzles. I just wish the spike underneath the door at the end was an actual spike instead of a reskinned muncher....

Something I'm working on (albeit very slowly...)

Room from the hack I'm currently moderating (Flying High Again by Noise).
I'm particularly happy with the flying pattern I used for the long 2-tile high tunnel near the bottom of the level - it is perfectly stable (i.e. could be repeated infinitely).

Unfortunate SMW fact: If you carry a portable disco shell through a pipe, even as part of a doublegrab with the shell in the higher slot, it will stop being a disco shell and revert to being a regular, boring shell on the other side of the pipe.
This breaks part of the glitch puzzle I'm building :(

I beat ColonThree, again, again, again (this time even faster!):
