Thank you for the detailed and constructive feedback!
1. Regarding the crafting: the orientation should not matter. Both versions should work ingame and result in the same output.
2. At some point I will try to include a tutorial. In theory you should be able to move with a really light and natural jogging motion without too much movement (check the video how I'm moving at the beginning). But I know that the gait can be very different for different people. I will try to do a user study at some point in the future and use this to improve the detection more.
3. For the inventory I am still searching for a good solution on how to do it both from an interaction as well as from a gameplay perspective. I plan to include at some point craftable upgrades that increase space so I did not want to make it too big in the first release. But you are right; a stack size of 4 sticks is way too small. For the tools: I want to create a toolbelt but did not get it finished in time for the first release... so I just put them into the inventory for now. Will change this in some future update for sure.
4. There is no ingame menu yet; the game will save when the Quest goes to sleep or you press the menubutton to exit the game.
