>>44530729just google "deviantart pokemon route" and you'll usually get a bunch of examples of what not to do. That's where I got pic related. The cluttered and thin looking paths might seem nice aesthetically, but trying to play with them is ass.
As long as you widen the paths in such a way that constant direction changes aren't always necessary, you should be fine. Doesn't have to be Gamefreak-tier "everything is a perfect and bland straight line with no imperfections or deviations" but make sure it's easy to walk through.
