I think the sound and the visual are very attractive. I am a little bit confuse when I first enter the game because I didn't read the instruction of the game. I am trying to push the ball into the hole at the beginning. Also after I dead from the level 3 I am not able to restart the game. So my suggestion will be 1. try to complete the game loop. 2 maybe add a boarder to the game that can limit the players movement. Finally! I really like your game animation.
