Hello, mate! I played your game and I liked it a lot to some extend.
I love the art style a lot! It looks beautiful and I have not encountered a place where I felt it was out of place. Maybe a bit to dark on some spots in the first level but that's a style choice.
I loved the ambience and sound design as well but one thing that destroyed my experience a bit for me was the movement.
The puzzle difficulty is good. I think they are good to understand but the movement makes some of them hard to solve. The player does not behave like people are used to since you can not rotate in a standing position. It is also to fast and you move in steps which are simply to big. The camera following is cool and stylish but sometimes a bit annoying since you cannot control the rotation. I would recommend changing the camera follow to a standard third person controller with some limitations depending on the puzzle. The auto climb was also annoying at least combined with the rough movement. I personally would suggest letting people climb by pressing space bar and using the oxiflame by maybe clicking with your mouse or something.
I know those are pretty standard inputs and finding different ways of moving is cool but the movement does not work at least for me.
Everything to the side, this game has a golden potential. Simply, fix the movement system and I am 100% sure you have an award winning indie game. I liked the art, the design, the sound, the ambience and the immersiveness. Good luck and keep it going!
