How strange, I have never died on that level, it is one of the most difficult moments in the game, but it is not impossible at all, although I admit that it is an area where one feels danger and tension, it is good that it is not as easy as modern games .
It's only at the final level that I feel that tension again, but the constant rewards encourage me to want to review everything.
with a little training in platform games it's very possible to beat that underground level, those crabs aren't even smart, they can be killed or avoided.
