Islands of Secrets

noticed some oddities:
- completed the first mission at level 20, started the second at level 19 and without artifacts (was that intentional?)

Um... artifacts are not carried over from one map to another. As for the level, I'm not even sure, everything is fine for me. It might be some kind of bug that doesn't depend on me (because in the editor, the hero is simply given a starting point for the player-created campaign, and he will be at the same level in the next map as he was in the previous one).

- in the first mission, the additional task of liberating the besieged cathedral after completing it (before taking the castle) does not have a checkmark in the tasks indicating that it has been completed.

I'll fix it:o. It seems I missed a moment in the script.

- in the second mission, there is a task to take any city within a week, so I missed the deadline by 3 days and didn't lose the mission, although the task is marked as a main one.

There is such a thing, I'll put a day trigger. But, thank goodness, it doesn't affect the Walkthrough:)

- in the second mission, when you approach the shaman's house, it first says that no one is there, after taking the castle, you approach again - it says that no one is there again, and then the cutscene starts immediately, and after it ends, it is not clear whether you need to take the orc castle or not, it would be good if this moment was described in more detail in the additional task or in the text, because you kind of want to be a good hero, but extra experience doesn't just lie on the road...

The shaman has absolutely nothing to do with the orc city:) That's why she doesn't mention it in the conversation. Capturing the city and mines is up to the player, but they are not particularly needed to reach the maximum level. So, I repeat, capturing it is pointless, and for a simple playthrough, you can just go to the portal.

About the orc's revenge: he appears with a small army and doesn't even try to take his own castle and increase his army, but immediately rushes to my second hero's castle, where he is easily defeated (I'm playing on the maximum difficulty level), this moment should be made more difficult...

The first two maps are just... a kindergarten. They weren't intended to be difficult. I advise you to try the third one on maximum difficulty. There, even on normal, if you hesitate, a demon with a huge army will appear, and it will be difficult to kill him:smile13: (it happened to me twice). But on the easiest level, he will not have this opportunity.

And yes, about criticism. You can and even should criticize (reasonably). But in this topic, only Ser9K's works are criticized;) and the uploaded mod in particular. Everything else is off-topic.
