Haiyoru! Nyaruani: Remember My Love(craft-sensei)

I got a similar feeling from these short funny episodes. You don't have to think about anything while you watch them, like when you're feeling tired but still want to watch some anime. :D 

The similarities are: Both involves a muchacho (male lead) having a realtionship with a hevenly being - even if it's a diety . Both involves a couple of additional hevenly beings living with the muchacho and giving the poor chico some cabeza del dolor (headaches) along the way. Both has one member of the household (if you can call it that way) whom the muchacho wouldn't wanna mess with. What's the diffrences: The muchacho in AMG is a college student, while in HN the muchahco is still in high school. One is a full anime with a season 2, while the other is a 4 min omake. HN is a pure slap stick comedy, while AMG is a combination of varous genre. And, one is a 3D anime, while the other one is a 2D omake.  read more 

Similar art style. Only 3 minutes long per episode for both. 

Same company doing with the same flash anime style.

Same type of flash-style short anime. Both have aliens.
