This is amazing!
I like how the lava both acts as a penalty and makes sure players don't fall all the way to the bottom. I'd love to see this more polished, there's a lot of cool ideas here. I imagine the lightning flippers were going to be checkpoints? I think I'd like some more control with hitting the ball, it sometimes feels random where it'll end up, and sometimes it ends up under the flipper after I hit it.
