F: Q: it's not mentioned in the 2.0 docs but whats going on with jump or swimming?
Y: For 2.0 we are remodeling all the maps so it requires lots of checks, so we’re talking about including this with 2.0 but just ending with that is kind of sad so here is one more spoiler, and this one is movie too



F: it jumped
Y: this one I said it’s jumping too high and said no to this one but strangely when it’s with this guy


(lalafel jumping)

 F: it’s jumping the same height?
Y: yeah same height but when it’s with him it doesn’t feel too much awkward, however this height is too comical so we’re still making adjustments like this and testing.

Also for swimming this will be after 2.0 but instead of just being able to swim we want to add stuff like underwater temple, or raid using water, and we’re talking about what to do about breathing air. We want to do it, we’re not to a point yet to tell the dev on what stance to develop this in yet, this will be after.
