Yes, well, I won't make excuses about not having enough time, etc. - it's just my own fault, and it all depended on my own attentiveness. My result is around 100,000, level 21.
Level 32 is still a long way off, but I do see that I'm not the worst.

:) I'm not making excuses. I just didn't have time to make the last two moves. Otherwise, I would have gotten 654,447 (level 31). I still wouldn't have reached level 32. So, I'll be paying close attention to Perpolken :) Maybe I'll finally learn something. :)

by the way, did everyone focus on Dungeon, or did someone rush to the top right from the start?

In my opinion, it was definitely a bad idea to stay in the Dungeon. You had to focus all your efforts on clearing the path to the airport on the island, as all the elf units there were weak. So, you could take them out in waves of heroes (this is only prohibited for mixed units, as far as I understand from previous discussions).
