I made an account just to leave a comment. I've been speedrunning this game for awhile now and it's still pretty fun. The movement is really fluid and Yuyuko was a fun boss to optimize. I found a few skips as well... (my best time so far is 2:31)
Very neat! I definitely built the game's moveset and level designs with speedrunning in mind, so it's great to hear that someone's doing it. If you get a really good time, I'd love to see a video of it and I could maybe offer some inside knowledge on the mechanics if you're interested.
By the way, my own personal best is 1:58 ;)
Oh cool! I have videos of my attempts, but I don't think I can shave 30 seconds with my current strats. Uh, to say what I already know, I know that you can basically fly over the tutorial area and that you can cancel dashes into jumps, as well as use this to get a lot of speed going up walls. I also know that you can double jump without using up an air jump if you do it fast enough (same as walking off a platform), and that if you have 3, you can use this to get past the part with the 3 cockatrices, without punching the thunderbird, but I haven't found this to be faster since 3 jumps requires too many eggs. For yuyuko I use dashes in phase 1, 2 dashes and 2 charge punches in phase 2, 2 charge punches in phase 3, and 5 dashes and 1 charge punch for each part of the last phase. (Sorry this kinda turned into a wall of text.) Anyways, if you have some insight that would be great! Also, I could show you my best time, but I think I'd have to upload it to youtube in order to do that, so it might take a bit of time.
