Hey, devs! Love the concept. I don't mean to sound negative, I'd just like to point out a couple things.
Firstly, I can't play your demo because I don't have Oculus. Nor do I have an account with Oculus. But I do own a Valve Index.
On another note, if you used the SteamVR Unity package there's support for nearly all VR hardware and you wouldn't have to spend so much time trying to figure out calculating throwable object velocity because that's all built right in!
It is my personal opinion that making a game Oculus exclusive is a real downer for the VR gaming community.
I occasionally read about the physically disabled community's love for VR, along with seeing requests for games targeting their disabilities specifically. You've really hit the bullseye with this project.
Best of luck to you on this. It appears to have some real potential!
