I enjoyed this game. What was really memorable about this game was the usage of paddles to bounce the balls around the game board. In regards to improvements, I think the addition of some UI that tells the player the controls would be useful. I think the addition of a scoreboard would provide the player with more of a challenge. Maybe if one of the balls falls through, the player receives a point reduction. I also would adjust the angle of the pink obstacles so the balls won't get stuck. One final suggestion would be to add a bouncy physic material to the pink and white obstacles to make the balls bounce around more. Overall, the game is very solid, but with some additions/adjustments, the game can be even better.
