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 :)
