As an experiment, the map deserves a lot of attention. I myself was interested in seeing how the AI would behave in non-standard conditions. Therefore, in this part, everything I wrote should be considered not as criticism of the author, but as notes for future reference. It is very possible that someone else will want to create a map with destructible castles.
As for the question of whether it is possible or not to play "in the same format," there are many answers, which depend on the tasks set. To avoid creating a universal off-topic discussion, it is better not to touch upon it.
