Hello. I downloaded the game folder but it looks like you shared your game editor files and didn't actually export the game. For example, it's like you edited a video but published the files that are in the video (such as images, sounds, and effects) but didn't export the video. So no one will be able to play it if they don't have unity installed. Remember to export your game so everyone can play it; I recommend you watch videos on youtube that explain how to export in unity. Bye bye.
