I just went a few rounds in this game, and even in its current simplistic form, it's a lot of fun, mainly because of the fact that you're dealing with slow projectiles you can dance and dodge around rather than hitscan bullets like in most other VR FPSs. It's kinda like Police 911 (Police 24/7 for the PS2 port), but with free movement and a retro aesthetic.
I do have a few suggestions in mind:
-I'm another Oculus Rift + Touch user, and the only beef I have that pertains to that specifically is that the gun's grip angle doesn't really match up to the controller's grip angle. I can compensate for it during gameplay, but it doesn't quite feel right, you know?
For a looser estimate, I'd say that holding the gun level, the grip is angled about 45 degrees up from my hand, the whole thing is shifted about an inch to the left and two inches down from my actual hand position, and of course, the pivot point when rotating my hand does not match up, either.
-I would prefer having typical Onward/Serious Sam VR: TFE/etc. analog stick movement. The grip button is workable for general walking around, but the moment I need to backpedal because there's an enemy right on the other side of the door, it doesn't quite whip around fast enough. No, this mode of movement doesn't make me motion-sick in the slightest, and I have yet to find a preferable alternative.
-Right now, the left hand (or off-hand, really, since these games should be ambidextrous) is just completely invisible, serving no purpose other than an invisible means of locomotion. I'd suggest having some sort of wrist computer (the Pip-Boy in the Fallout titles being one of the most iconic ones) present, serving as both a mini-map (it's easy to get lost in these same-looking blocky rooms!) and an indicator of the player's remaining health. (EKG-ish readout like Blake Stone, perhaps?)
You did mention in a recent comment that looking down now shows your health in 0.0.3/0.0.4, but the currently posted build is clearly a bit behind. No health indicators, no food, no security robots and no quadcopter killdrones.
