I generally take the standard route until about the jungle or so. I keep my eyes open for wands+spells able to dig through holy mountains, teleport wands, and wands capable of bringing down bosses like Squidward and others. If I find them, I jump the rails and go do other things, if not I focus on just beating Kolmi. I generally can take the first option 1 time out of every 5-6 tries, though I am sure I could do it more often if I was better!

I am once again reminded of the always relevant XKCD comic

I do see and understand the concern, and honestly, I don't see a way around it. At some point, you have to supply some information to access services, especially if you want any sort of customization to your experience. I guess if you are really concerned about it, don't use that email/password/username combo anywhere else.

Edit: Apologies, I am still figuring out how formatting works here.

That got a belly laugh from me! I work on code dev, and I am totally stealing that.
