I really enjoyed this mission, especially the navigability of the map (esp. when searching for all loot and secrets).

Only thing I might complain about is the number of frobbable items that were of no use (forks, bottles, etc.)

This is such a pointless complaint. Why would having random frobbable items ever be an issue in this mission? It's blatently obvious what items are treasures/objectives.

The random objects like boxes, bottles, chalk, whatevers all add to the immersion. It's a wizard academy full of lived-in rooms filled with stuff. They're objects. Objects can be picked up. You don't have to pick them up. They _can_ be picked up if you want to though, which is what happens in real life. You can pick objects up in real life too.

It's possible that some new assets (especially magical items) look similar to treasures, but in the end they are just regular items.

If someone is motivated to collect 100% of available loot, they will be checking every item they find and haven't seen before.

FKenFord is right that when introducing new items in FMs, its better to leave most of new objects unfrobbable. On the other hand, forks and bottles don't seem like a good example of valuable items.

Hal is right that leaving them frobbable increases immersion. The immersive sim aspect of gameplay is that the player will check every item and see if the item has potential loot value. To immerse themself into the main character, the player will try to remember which item they saw already before, and will try to tell if the item has a loot value, without picking up the item.
