@Derpy IIRC there's a few hard hurdles that should be insurmountable without entering the Incrementiverse, but the number seems on the low end compared to what I remember. You should be able to get a total SL of 616 or so to Open the Portal.
> Manifolds are gained after resetting your Incrementy, which can only be done once your Incrementy Multiplier is higher than the Incrementy Multiplier requirements for getting a Manifold, and is capped of 398 if you are not in the incrementyverse.
I haven't actually checked my Ordinal markup in many days... after a few rounds of cardinal+manifold -> Omega 2 -> Omega 5 -> Dark manifold -> Cardinal grind, it got kinda boring
If you REALLY want another timewaster though, a lot of my friends are playing this one and I'm trying not to, due to deadlines: bloodrizer.ru/games/kittens
