I thought I made the game friendly enough that everyone has little challenge, but still can beat it. My plan was not to make it frustrating. But the hint of extending the shrine power times sounds like a good idea for the difficulty setting!
For handling difficulty, I originally wanted to have more paths for all levels, a short one which requires more skill and a long one which is easier but taking longer. But I ran out of time for this.
