Yup. After my first time going through it in Yellow, I never needed Flash for Rock Tunnel again. In RBY, you could still see all the walls, so navigation was easy, and in FR/LG you get a small circle of vision, so it's harder, but still not all that difficult, considering how many times I'd already been through it. --- You fail at life.

Even when I was that young I didn't like wasting a moveslot on it.. Remember being stuck with Cut on my Bulbasaur though! --- http://lparchive.org/Pokemon-Blue/Update%2011/39-capture_13052010_205404.png
Yes, but it was mainly because I wasn't aware it existed until I went through, kept thinking to myself "This is a horrible idea, why did they make us do this?" --- Pokemon Black 2 FC: 5372-8212-5739 3DS Friend Code 0430-8284-1167
