Cool idea! Reminding me a bit of the we were here series. It was hard to know which way the VR player faced. We get now that it is the chin of the skull but in the beginning my friend that played on PC thought that it was some form of icon of the headset.
The teleporting movement did not work perfectly for me, somehow it got stuck in like my hand/key? So I ended up teleporting just to the same position that I already stood. For my friend it was kinda confusing when teleporting (she has not played that many VR games) since the map was so similar it was hard to know where she was after teleporting.
Another friend wanted to be able to show me and interact more. Like maybe having the mouse be visible for the vr player. I think that could make it too easy to just follow the mouse but it is a cool idea and might be able to work in somehow (limited time maybe).
I found a fun way to play where I stood behind my friend and directed her to always face in the correct direction instead of shouting left and right.
The models for the keys were really cool!
