This is a cool game idea! I like how you took a classic arcade machine game and remade it. I think there is a lot of potential for a roguelike, because you could have something like special types of balls (maybe explosive or homing or bonus points) as well as special pins to knock down in different types of rounds. It definitely could work as a Balatro type game where you just get as many points as possible.
I think the demo could really use some sounds to give it an arcadey feel and also to help communicate when a ball is picked up, thrown, and scores points and such.
