The two entries share stories about sensitive content in the life of high-school girls, with the similar animation style being flashy and abstract at times.
It made me actually think that Ruru's animation was some kind of promotional music video for Wonder Egg. Music taste may be individual, but the content is very similar, so if you liked one, give the other a try! I am sure you will also get the same feeling.
