Today I found a new trick that allows you to skip most star doors in the game (the 10, 20, 25, 33 55, 70 (the textbox mainly), and the 75 star door. Here's the trick in action https://gyazo.com/7a0dfb2265544711451920336fea8cf3

Here's the catch: I could only get this trick to work on version 1.1 If it was possible to do this on 1.0, we could use the BLJ to skip the 50 star door. However, we cannot, due to the BLJ patch added in 1.1. So we need to find another way to skip the 50 star door (so we can get the green switch). It's possible to get every other badge (methods shown after this paragraph) with only 0 stars (although if you need the super badge it probably would be faster to grab the fortress star). And it's already known that you can skip the 85 star door. As well, I found a place where you could skip the 40 star door in 1.1

Badges: Super Badge: Use the backflip trick to get through the 10 and 20 star door, then get the super badge as normal Wall Badge: Use the super badge to get into OW2 and use the backflip trick to get in the door, and then get the badge normally Ultra Badge: Get a few firsties in between hot blue mountain and the 50 star door to get on top of the ledge and then go to icy temple of time 2 and get the badge Triple Badge: Same as normal except backflip trick into the level.

1.1 50 Star door skip has been a thing for a while. You can ledge grab the roof above Rainbow Road, go up and to the side, then jump to one of the end platforms of the path. As for Super Badge you can just bomb clip the door, and for WK badge you can chuckya clip it either with a LC or walking to the spring and doing a dive right after being launched.
