The player is never mistaken. They are just different points of view and sensations. Some people find it difficult and others see it as logical and easy. There are even people who told me that the peddler puzzle would now be too easy (the noise of moving the figures I added later).
It is difficult to find a balance in puzzles. But I am happy to listen to all opinions to make it better and better.
And thanks again for playing the demo and telling me your opinion!
