Cave Story.
My best time on the Sacred Grounds is 4"24'3.
Now, I know that none of you here are anywhere near skilled enough to make it through the Sacred Grounds alive, but I just thought I'd share that.
On a related note, I'll be making a Speedy JQ based off of The Sacred Grounds, and putting it in place of Hell (The place below El Nath mines).
It will be the final leg of the Ultimate Event.
