Yeah, it's pretty old school. I think Mataasi even pulled off the duicide 360 exit.
I don't think that a double 3d sprinkler would be possible...
it was inventad by malte, in M.A.L.T.E. at the end.
Wrong. I've seen it without the 360 before him by Will C in MJC Collab 08, Part 2. Unless you were talking bout the 360 part.
It didn't feel too difficult. Funny thing is that I propably was trying those out while Jussi wrote it here... Strange. No 3d sprinklers for me, yet at least.
