okay yeah I will try this specifically then from I gathered, from your reply, you did not embed the .pck file with the .exe of the game. I also added rcedit and signtool to the project settings which I thought might help the issue but it doesn't for me. And I've tried to do a Web version of the game and theres missing sprites, I believe i've tried everything for that apart from rolling back the project to a more stable version of godot for web games but that seems like a step too far for the time being :D.
I also played your game, I like the style : ). I know it was mentioned that the games has loud audio (in the comments if I remember correctly). It might be a bug or something but you can manually turn down the volume of the audioplayer nodes, which only works when you run the game in engine as the inspector will play the default audio clip regardless of changes. That atleast worked for me, but the slight compression is still apparent.
