I love the diegetic UI stuff. Interacting with everything in-world really heightens presence. Also the forced aspect ratio is claustro as all hell, to the game's benefit since it takes place in a tiny sub. I felt like I spent a little too long holding W and watching coordinates change instead of paying attention to the window since there was often no point of reference outside, but that disorientation is also definitely important to the overall experience so ¯\_(ツ)_/¯
Overall it's really good
