A bit unfinished, but off to a great start. I'm impressed by the high quality of graphics and having what sounds like proper voice acting. 

The level design looked also great. Unfortunately I feel like I hit a dead end when going to the light house and running around on the water. Also halfway to the light house I started seeing the character model of my first person in front of me...in a way that didn't look intentional

Very good looking but not quite functional yet. But it's only a week long gamejam and you pulled a AAA-looking prototype with even voice acting and a good one!! Congrats I feel a little bit of a Thief vibe here. With more time I already see the potential. Good job!

Liked:

-AAA Aesthetic that doesn't seem to be made using bought collections.

-Good level design --> GREAT framing and usage of landmarks!

-Voice-over dialogues

Disliked:

-Controls are very rough

-Dialogues glitches. I had the same dialogue start like 3-4 times, overlapping themselves with little delay..

-Very good looking but unfinished. Looks like a prototype of an intro. But after the lighthouse pointed its light at me I had no clue what I was supposed to do. I found that I could walk on water and just had fun walking above the waters and contemplating how much the water looked great :)

It was a little hard to figure out the objective, and the lighthouse was a little blinding. 

However, the visuals were lovely, and the voice acting was really cool! I especially liked the voice line when the lighthouse thing spots you.
