Damn, a whole essay for my game? Now I gotta check your game out.
It is true that the audio samples aren't mine. However, the monster sounds did not sound like that out-of-the-box. I edited them to sound the way they do. The original breathing sound was just a generic "main character breathing" sound effect. But I edited it in Audacity to until it sounded creepy and uncanny. Where it seems kinda human-like, but something is wrong with it.
(Also fun fact: The sample used for the monster death noise was from Super Minecraft Kid screaming.)
As for the wood bug you mentioned, I think I might have encountered it before. I assumed I just forgot to update the HUD. But if you can't add wood to the fire anymore, that's probably a bit more concerning.
But yeah, thanks! I'm glad you liked it!
