Played a couple times - very impressed! I'm not usually one to comment, but you need to know, this is so unique and has *something* 80% of other VR games don't have. You've got something really great in progress here - keep going! (I know it's very early, so I'm sure you know, but players could use some tutorial/explanation for the ammo/energy and control stations/levers.)
Watching a video while writing this that said you wrote the engine from scratch, or didn't use Unity/etc. 100+ more impressed points for you!
Really, really cool! Thanks for putting it out there - and again, keep going!
