Rock of Ages.... just... rock of ages.
Still can't beat it xD. I probably spent 20 minutes in a single part and I still have no idea what I'm supposed to do (you need to jump on a white platform and then on a rock platform that's higer up and I just can't get there).
We have stuff like this and people seriously say Dark Souls is hard?
That part took me about a good 10 minutes. The part right after isn't much easier, I got stuck there for about another 5 minutes and accidentally hit restart by accident instead of last checkpoint.
I was too sick at myself to continue playing.
