For starters, I recommend you give instructions on the installation process for Mac users and maybe Windows users because as I downloaded the file, it stated it was damaged. Fortunately, I ran into this incident in another gamejam, so I just had to show the package contents and run it from inside the file.
Now for the game, I overall enjoyed the arcade style approach to it and the surprises you added to it.
My suggestion for your game though is to increase the pacing of it. For the pong game, the ball took a really long time to move back and forth between the me and the AI, which I feel would cause a player to lose interest quickly, especially if they are thinking its only just a pong game that might take a long time to reach that surprise.
Nice game entry overall though!
