It's a fun game, though as you've asked others for feedback:
I would suggest maybe trying to get more interactivity with the world. Being able to pick up and move objects in VR, for example. Having that hand interaction and vibration on feedback is one of the best things about VR to make it feel real, so those sorts of physics aren't things you should skip out on.
Perhaps it's been changed in an update, but having to hold down the grip key in order to hold onto the sword gets tiring. It would be more enjoyable to have the option to simply hold it automatically once it's taken out.
The magic system can be a bit difficult to get the correct spell and throw it, though that may just be my own lack of coordination.
It looks like a good game and I will be interested in seeing what the finished product looks like.
