You have played this kind of brain teaser many times, but I don't think you have played such a challenging thought-provoking game before. Now feel yourself in a sea and there are many obstacles in front of us and you can move these obstacles with a single move without getting tired. Your only salvation from this sea is to pass through the door by taking the pieces of wood in front of you to the edges, that is, to the gaps, without compressing them. The game gets harder with each episode. In these challenging missions, you can pass the levels quickly with critical thoughts. Have fun.
