Are you teleporting between different elevation or panning the camera fast, or something, when this happens?
- Funny blue glowing shader on stones, doesn't seem to be there intentionally
I believe that is a highlight for shallow water. It could probably be more subtle.
the player has no immediate reason to go in there
One character does say that the leader mentioned escaping with a stone, and the other replies that it was probably stolen from the dungeon and asks if they can get inside. It could be a lot more visible, though (I missed the first comment as it happened as combat was ending, and I had to scroll up the log to see what the other character was referring to).
I am not a fan of tutorial levels that give XP at all unless they are a major part of the plot. With this you are forcing completionists to always play the tutorial level and even me, who is not a completionist, feels compelled to run through it to get the xp and earlier level up thanks to it.
Perhaps when the tutorial is done you will have the option to seal the dungeon, rather than enter it, which would give the same experience points and loot as completing the dungeon. Alternately, there could two paths in the dungeon, and a dual dialog triggered about whether to take the shortcut or fully explore the dungeon (that would make a pile of loot more reasonable than just sealing the dungeon).
