I agree with the posts above - I was also unpleasantly surprised when Vitya repelled the first catapult, and that requires a lot of resources. This raises the question: WHY?! Or at least add this information to the task description; otherwise, excuse me, it's like hitting someone with a scythe. But overall, the map is good in terms of its concept and difficulty. Good luck to the author!
The task description mentions this, although it doesn't specify the exact amount.
