Well, I think that your game is very beautiful, nice music, the idea of a store in a computer, and that you can buy spell elementes is nice, but, you need somehow a theme UI which starts the game, there you can explain the mechanics, the goal of the game and a brief story of yout game like the story about your main character, then you can add buttons to play the game, adjust settings like music volume, and the credits of the creators wich you used in your game, I hope you good luck with your project in the jam.
