I'm guessing this is one of your first games in godot, or first time of engaging game dev, so I won't be so picky. I think this is a great start, and the game mechanics are totally fine, but the camera is a little bit too zoomed in for my liking, and it's difficult to see where I'm supposed to go. I couldn't find the theme usage in this game though? The main menu could also use some more love, but other than that I really don't have any complaints.
