After around 2-3 hours of grinding (between two sessions) I finally got a good time! The hard part was first just trying to figure how to get proper height to even get the ceiling hook to connect, but after I while I figured that you want to sort of hook on the way down and that really helped me.
Now I did get improvements prior to this run, that being a 8.76 and then a 8.71 but both of them had a sloppy ending, where I didn't enter the door instantly and instead went kinda past it, losing time. But I kept going as I knew the time I wanted would eventually come, as it's not really that difficult of a level, just have to be patient until all the pieces comes together.
I still have room for improvement, seeing as とおろ has a 7.95 (which is the run I copied). Which is mainly the slow start, where I stopped between hooking the ceiling slightly. But that will have to be some time in the far future.
I've been thinking the last couple of days of even more changes, albeit not too large ones. The biggest one is the removal of the 3DS version. Both me and Ico came up to the conclusion that it's too different, essential "a different game".
This is due to it being: 30FPS, 10 Less Stages, 5 Less
