The style of this game is very cool. I really liked it. Everything seems to run well. The attacks work and feel effective. There's plenty to explore and learn about the world. I think the dimensions are a great idea, and are expressed well with the static objects.
If anything, the mouse sensitivity is kind of low. A slider would be appreciated. Also "f" to interact feels a bit unnatural to me, so control remapping would also be appreciated.
Great job!
