I was making a new run for the Normal ending category where I was trying a new route after discovering that you don't need to fight a expert version boss to unlock the robot chapter. Actually all you have to do is to clear the dialogues before you enter the area of the boss and then go back to the bunny train. (I won't send my run yet though because I want to optimize it first and not bother the admin with 10 hours long runs to verify)

However when I ended this run with a good 2min30sec WR gap, I started to spam my spacebar for joy and in the video you get to see what happens : the ropes that where suppose to be cutable only after a +1min long fake credit got instantly cut even before it started. I don't know if this is replicable yet but if that's the case then the true ending category just have a new +1min skip.

the normal ending skip is really nice how'd you figure it out?

I wanted to break the 40min barrier so just like whenever I'm stuck I booted up a new game and messed around to see if there isn't any other strat/built for a boss or in best case scenario a skipable cutscene. That reminds me I still haven't talk of the robot cutscene skip I've used since almost a year. I know there is a guide category on speedrun.com I should take a look a it.

that's actually a nice little skip i thought you had to restart later on when the robot actually appears as with some bosses like aya second stage where if you restart too early it will put you back to the first
