Thank you for the feedback. This was my first full-made game and I feel it was not a good one. I wanted to add some other features, but ended up going in over my head and running out of time. I was afraid my game would not be fun, and it seems that is how it turned out. I will keep this in mind as I develop future games :)
Also, for the audio, I have no idea how to fix that. I have tried my game on three different devices and it worked on all of them. Do you have any suggestions? I made this in Godot 3.5.2
