Thank you! Ah, when I created this game, I was extremely new to Unity so I didn't know how to publish it correctly. For example, I left the fullscreen option on because I didn't realize that despite telling Unity what aspect ratio to set for the game, it ignores that if it's on fullscreen! The blocked dialogue text problem might be because of that. Also, the game indeed has no sound. Thanks for the tip on tar.gz! I don't have linux myself so any linux problems I do apologize for.
