I am playing LoG on an iPad Air (that's 2 or 3 not sure...)
The game is great except for one thing.
The text on the walls is always one of two sets of symbols. I though this was deliberate until I read some walkthroughs where it's clear the text is meant to be readable and gives hints to the puzzles. This makes, for example, level 4 especially hard.
Any idea how to fix this?
