That's like the best response I've ever seen in any thread about anything. Thank you very much jimsfriend. I'll comment on the images individually:
1. This one I have already thought of.
2. I don't think passing through slopes like these is possible. If someone made an smv showing it I'd gladly be proven wrong though.
3. This one I have already thought of.
4. When I did Crystal Cavern 1 in our SDW movie I experimented a bit with lava, with results you'll be happy to hear about. You can indeed fly under lava, and another cool thing is that you can fly up to the "lower edge" of the lava, and go into swimming mode, in the lava, without dying. You can only swim in the lower parts of the lava pool though, if you go to high the game catches you and you die. Not useful of course for any speedrun purposes but cool to know. I should have an old .smv of that (that whole level was discarded when it was pointed out to me that I was taking a route about 60 billion times slower than the correct one. Great job by me), I'll see if I can find it and edit this with the link.
Edit: Bah, I hadn't saved it, so I made
this instead (it's for Super Demo World btw, not SMW).
5. Fantastic! I haven't thought of this before, and I probably would've missed it, so this is great. I'm not sure when the earliest moment you can return to the ground is. If you fall quickly enough to be able to reach the middle route in that last labyrinth section (where the green shell is) without hitting the wall (while ducking), you can fly up on the ground and start hopping any time after the solid wall just after the two yellow blocks, or at least after the 5 spike guys I don't remember the name of. Otherwise you can do it just before the goal post, killing the chuck in the process.
6/7. This one I don't fully understand. From where do you run up to flying speed? I think this should work, what I'm not sure of is why it would be possible to fly under box 2 but not box 4.
8. This one I don't understand at all. Unless I'm misunderstanding, you're passing through the slope without flying? I also don't get what "DEAD" means in this context. It should also be possible to do this without beetle, although that might be slower. All-in-all about images 6-8, this will take some more experimentation I think.
9. I just realized that some of the things I've said so far can be disregarded. You can't fly up through these walls/grounds while flying underneath the level, can you? I mean, except if you do it where there is an angel or something, but not just regularly. Oh well, time will tell. This should work too, thanks a lot. Also, if it does, keyjumping shouldn't be needed, it should be possible to simply fly up to where the keyhole is.
10. If 9 will work this should too. And I think it will. Thanks again.
11. I don't think this will work. I think hanzou experimented a lot with the swimming mechanics in Water World 4, what do you think about it hanzou?
About the extra lives in YI2, if I hadn't already done that level, I probably would get 5 lives now. It won't cost any frames, and while I think the other method might be cooler in general, this one hasn't been done in a TAS, and one of my top priorities with this movie is to show off new cool stuff. Maybe this will be in the final version, I'm not sure.
Thanks a lot for all this, it was very helpful. I hope to see more of you around here! Now I'll go look for that lava flying smv.
Edit: Added a link.
