Question about the map "Longest Journey".

I finally found my save files: you didn't take too long, I landed on the shore near the blue player on turn 3-2-1, and Khalid had already taken the rusty dragons from him. Then he didn't attack but got into a boat, which I took advantage of. I was also playing on 160% difficulty: I try to stick to the difficulty recommended by the author in the map properties, otherwise the task may be either impossible or too easy.
Overall, this map isn't too difficult; it's just important to do everything in a relatively timely manner. After defeating the brown player with a lot of Towers, you become quite strong relatively quickly. Then you need to defeat the pink player ("master of the seas"), who can cheat and fly across the sea and reefs to the west, despite the author's clear ban on flying. After that, there shouldn't be any more difficulties.

I didn't know about 160%. I try to stick to the difficulty recommended by the author in the map properties
Where can I find out about the map properties? I've been playing for a while and haven't encountered them. If the set difficulty level is the thing, then it's impossible, so it's 5. But it seems like I'm missing something.

Regarding the game, I looked at the map in the editor (which I don't like doing) and was a little disappointed... almost all the monsters on the world map have random levels. That's why I couldn't beat the Efreet Sultan's guards for so long (I ran around for 2 weeks).
Still, it matters whether it's these fast creatures with a fire shield or some Manticores, on which you can immediately cast Slow. I'll replay it on 160%, and at the beginning of the game, I'll reveal the map so that very unpleasant creatures don't spawn randomly (especially those with speed, which gives them the right to go first).
