Ease of use suggestions

[blah]

Played through the demo level on the Rift. There's the start of a decent puzzler here and I'm interested to see how the game develops. Here's a few basic ease of use suggestions.

- help menu displaying button mappings

- Not sure how typical I am, but horizontal rotation (yaw) is the only aspect of VR that makes me nauseous. That type of movement is needed for games like this but there are ways to make gentler than it currently is.
-- add some motion blur and vignette
-- or just skip all motion and instantaneously change the image. This only works for fixed 45/90/180 degree rotates, 90 is best in that case.

- I found it awkward switching between 2 buttons to move. The fwd or back on the stick/pad could be used to activate the teleport instead of the separate button. That can be combined with left/right for rotated teleport like many VR games do.

- inventory is neither obvious nor immersive
-- I had to look to far down to see it and pull my hand to close to my stomach to get at items. Needs moved up and further forward.
-- over the shoulder or behind the back motions are used in a lot of games for immersion. Could also be open/closed with a button.
-- I kept accidentally putting things in the inventory mixing up the grip and trigger. The options above make the action more context sensitive.
