Okay; that's definitely one way I've managed it, but most of the time, jumping there just gets me into another wall run, which takes me under the overhang. I've never found it easier or more intuitive than, say, running up to the top of the left wall and jumping over:
To be clear, it's not a big issue (as I said, I've solved it several different ways), but it does feel like there should probably be one solution that (once you know it, at least) feels like the obvious solution. At least for the main storyline puzzles; secret puzzles can be as obscure and non-intuitive as possible.
And yeah, that makes sense about the attacks; would it make sense to have a tutorial popup about them?
Oh, I guess this doesn't really have anything to do with the demo, but I was wondering if you were planning on adding swimming as a mechanic at some point later on?
Thanks for your reply.
