The simple ideas are the best, your game makes me remain the arcade games, the mechanics of the game are very sweet, I think you need a start UI where you show the title of the game, some images about the game, and the mechanics explanation. May be you can show a brief story about the main character of the game, and buttons to play the game, adjust settings like the volumen of the audio and the ilumination, and a credits button where you can show us the creators of the assets that you use, your game is really good, best of luck in this jam!!
