The linux version should work fine without a vr headset. Perhaps it is an issue with the hand position? You can try moving the hand closer/further away with the q/e keys (right click to show the hand position). Perhaps that will help.
The q/e keys do help. Now the interactions start making sense.
Did not manage to make fire or fish yet, but I’ll start a new game now that I have learned how this works.
Maybe an instruction text or tutorial would help players like me. I did know the q/e keys, and tried them with fishing rod but could not figure out useful purpose for them.
Thank you for prompt help.
