Looks like a trippy game. Didn't see much of it tho. I got stuck at the start. Tried to say something near the boulder but clicking the talk button wouldn't send my message.
You should hear a response from an npc. this problem is kinda hard to diagnose because that part actually works on my machine for some reason. So, try restarting player2 API.
The PC build should work seemingly flawlessly tho.
