Okay, this timeI might be really lost:
I am in the rune temple.
last skill I got was the gap dash thing.
Am in the rune temple. cant do anything there.
top is the weird eye portal looking thing, middle green carpet.
bottom left flame book, bottom right fog.
cant do anything in there.
explored everything else (according to map also).
only map wise to the left in the dark brown area towards the top the long room there has an exit to the top right I cant go cause purple crystals in the way.
a bit further to the left, in the gray area, there is a tent at the top and a rock at the bottom right next to it.
there, bottom left of said double room, I cant continue either cause purple crystal.
Now I dont know how or where to continue.
was the other guy right that I should have gotten another rune/ability by now, maybe from those brown like yetis?
oh, and of yourse, in the serpent lair I obviously cant continue either due to purple crystals :-/
