Yea the audio was glitched in the uploaded build. There was never any music, but there were ambient sounds and some interaction sounds. I have it fixed but I'm waiting to fix some other issues before uploading the build. Thank you for the feedback .
Yeah, I think I messed up doing the whole puzzle aspect. You're supposed to craft a raft & paddle to get across. Thank you for pointing it out, I'll try to put up a fixed build soon where it's easier to understand.
I just uploaded a fix, you should now be able to consume it on the ground by pressing "E" or consume it by clicking in the inventory. Thank you for pointing that out.
