Can you please tell me what should I do to add the lacking concept, Thank you so much for your valuable feedback.
try to convey a certain way to solve each puzzle that each unique.
For example, you can convey that the orientation of the die matter, by giving the player easy step one a number tile,
which will make the next number tile impossible, and thus you taught the player the importance of orientation
I liked the one level that the number of moves was extremely limited, it forced me to think carefully.
I don't agree with the comment you should remove it entirely, It really depends on how much it is integral to the solution the number of moves. maybe give an option to play without it.
