I like the idea and design. Thank you.

@Adiorama Yes, you are right. The way in which the stack is made is original and non-standard. But, I immediately guessed, because I recently used exactly the same method on my "Sailing ship" level. I even have a demo video of this stack method

This made it easy for me.

@Denis Nazin in fact, I have thought about this way before, but I think that way should not be easy to operate.

I enjoyed it. Looks simple but puzzling.

@Denis Nazin Denis introduced me to this level and I played it. It was a fun and good level, but I had a different solution.

Spoiler: My solution
