My thoughts, some are from my google docs feedback

My feedback.
Please remove modern elements from the level design: the industrial metal mesh (for example, on the bridge with a guard who needs to bring beer) and barricades made of sandbags (near the exchange point). They knock out the immersiveness, and are relevant only in Elex.

All motion initiation animations start with a noticeable delay.
The item collection animation should be much sharper and faster.
Conversations with characters start with a delay of a couple of seconds due to the animation of the NPC's turn.
All animations of the rotation movement, when controlled with the mouse and keyboard, are clumsy.
When you slightly press the go forward button, the character should take a small step with a separate animation. Rather than wobbing with his running animation forward and back.
Overall, main character's animation and controls are main reasons of frustration while exploring.

Combat system - I don't understand how different types of strikes differ.

The structure of dialogues - different branches of dialogues should return to the beginning. It is unacceptable to choose one of the topics of conversation and deny access to other topics. I talked to Orry, asked him about the factions, and I lost the quest-related option to ask about a place to spend the night.
In fedex quests, there should be an option to give away the desired item at once, if it is already in the inventory (beer), without having to restart the dialog.

Graphics. The image exposure is too low. Shaded objects should never, under any circumstances, look pitch black.
Some typical UE5 problems - the anti-aliasing is too blurry, and vegetation elements are often unreadable mess at medium distance.

Overall, great impression from demo. Atmosperic and arousing interest.
