Cool idea (I like this kind of 3d adventure games with puzzles) but needs polish. For example- there is a hint, that mousewheel rises, or lowers the lantern... but I don't think it does. All of the shadows are rectangular, which would make sense for the blocks you encounter further in the game, but not the first statue.
As for the presentation- the main character was cool but some of the other stuff felt a bit clunky. Sound was limited, but I guess the night sounds fit the atmosphere, so that ok.
The atmosphere and puzzles were the strong part of your game. The ending was cool too (the sculpture was the best visual asset of your game)!
Over all- I think the project was a bit too ambitious for a 4 day jam, but I'd gladly play the more developed version of it! Keep it up.
