Actually, Lace told me about that, one reason I decided to pop my head back in for an undermined amount of time.
Also totally didn't notice the move, though I think they talked about it before I disappeared. Did notice the new layout, wonder if I'll change from my old Cave Story Lite now...
And naw, I wasn't around when he came back. Did just message me a bit ago, though.
Mathematically, no, I don't.
I do know another way to find it, but you have to do the fun mathy way.
f(x) = whole integer.
f(x) > f(x-1)
mebbe it's an iterative?
