When i was practicing speed running castle i notice there are a lot of objects to jump on in the game so that me got thinking could we glide or fly to the end with the objects? (Because in dark and steam you use the axe or stick) I don't think that it would save time for the better players because well, castle can be beaten under or around 30 seconds. So maybe beginners could use this but i don't completely know if it works yet.

It may be useful for beginners but what thing can fly in the castle？？？

Maybe the big stick to open the bars

I think the fastest way for beginners is after you open the lock is to go left and use the window to climb across and open the door.

in the very early routes for castle we used the catapult which was pretty easy. I'll time stamp one of my old runs.
