The intro is fabulous!
The free look option kind of reminded me on the movement in Operencia (which I am not a fan off) but I noticed that you put options in the menu to make it less disorientating (good!).
I like the mouse aim in general (like in the original Xenomorph by Pandora 1990) and I am also using mouse aim in another crawler project but instead of a fixed center aim just a regular moveable mouse cursor. I found this to be much better aligned to the needs of a DC and way less disorienting. You may want to try this too.
Nick picking aside, I liked what I saw and would not mind seeing a post jam version.
Good job!
