Use the world peace route and replace some moons
If time ends on Klepto, you could skip butterfly :P
The butterfly in Lost is also considered a bird, you might include that. Otherwise, I feel like it's too close to any%, only Sand is different... Maybe you can find bird-related moons or other goals in at least some other kingdoms. Maybe even just scare some birds away
There is already a thread about this called "1 jump category?"
Jumpless will become a category, if we get 5 different runs of it
One of the mods said that this will become a category, if we get at least 5 different runs ;)
So I did a Jumpless Speedrun today, I used 2P in the last phase of the bowser fight and returned to 1P right after the jump. It's a pretty fun run, as long as you don't accidentally jump lol. I used most of the any% route and changed some moons that were hard/took too long without jumps. Wooded needs to be rerouted though. Video:
