I'm really happy with this run even though I made a few minor mistakes here and there. I'll be content with this for a while, and I hope that more people start running this game so I have some competiton !! Come on people !!
Notes about this run:
I had to have done about 50 or so attempts when I found that you can skip having to run farther down the first corridor and instead you can jump on the rock to the left which saves a good 2 seconds or so.
Another thing that sucked was having to reset on not getting the fast sign clip, which is where you instantly clip through after landing on the sign. I got a pretty quick and clean one in this run and thats all that matters.
At the top of the land before you need to long hover, I accidentally didn't jump and was really nervous but ended up making it. Also, after springing, instead of going left like I would normally do, I tried going straight ahead at suggestion of doughyguy. I don't know how much time it saves but it appears to be a lot.
Fortunately my climb went really well. I could have probably saved a small amount of time by dropping instantly into the boss chamber, but I clipped off the ledge before the hole.
The boss fight went OKAY. I've been trying out a new way to manipulate the boss into spinning quicker, and it looks like it worked decently. I could have hit the 2nd to last rock a little faster and lava damage boosted into the treasure room a little quicker.
Overall a solid run. I'll probably do more 100% runs now which will be even more of a nightmare.
