The name Gnop Gnip still makes me laugh :D
It's fun to play, but it took me a while to understand that the other paddle must not leave the screen on the left side. A visual indication that the paddle bounces off of the other sides but not off the left might have helped. I also encountered a bug where the paddle left the screen and the game kept playing.
Once I got how it works it was definitely a lot of fun and the presentation is very good!
