need help for "the frozen mountain"

very nice level through a little  hard for me ^_^



I am stuck in the blue carven(flood carven)

with the postion x982y982, there is a waterfall to stop me from going on, I can't jump through it. I had try to stand on the edge, jump up and forward. or run to jump once. But both can't work. I had try to run and with double forward jump, but it seems the space is too narrow for me doing that. I can't make the second jump done.

As far as I can remember, that's either a secret dead end or there's another way around via water tunnel.

ya

if I go up and right, it is a road  to the heaven

but if I want to the paper world to get the eye,

maybe I need to go through this way

That's a dead end. You need to go the other way.

OK, I found that

there is a place with water which you can't jump to it(will die) but can climb into it

 

so I thought the x982y982 is the only way that I can go
