I like this a lot! I like the simplicity of the board design. I like how the colors pop against the black background, visually appealing. It also functions well. I think something to notice was that when I used the flippers, the ball seemed to bounce up on its own, even though the ball wasn't anywhere near the flippers. Also, it reminds me of the 3D Space Pinball game I used to play as a kid, so maybe the game could benefit from some cool space music and sound effects!
Other than that, it's a really cool project.
