The bullet-time mechanic is a lovely touch for "Pong", and the two different level styles are well done as well! One time very cute-sy, one time vaporwave-stylish. It's a surprisingly good combination and that are the reasons why I added "Ping" to our compilation article about the FEMICOM Game Jam #4. :) It's also featured in our compilation video. Let's hope that some more people will play this nice little game!
Best wishes,
Sebastian
