Wow, very nice! I always love rpg's with quircky stories and nice humor. The graphics do remind me of earthbound, but the combat system with lots of different enemies and different reactions to your attacks also reminds me of undertale, wich is coherent considering the close relation between both games. I also LOVED them both, so I'm really looking forward to this.
About the pixel art and animations, I really loved the personality of roopit and boopit, I think it standed out as a very unique expierience and I haven't really played anything like it. This game has a little less personality in my opinion, but its true that the pixel art and color palette looks more polished and professional. Also the rolling/dashing animation looks amazing!
I also have to say the game sounds amazing, the music is really, REALLY good.
Anyway, I'm really looking forward to a playable version and I will be waiting for the next video as well. I will also think of names, but I'm absoluteley terrible at it hahaha I still can't decide on a name for the game I'm working on... How about "Cat-powered space oddisey" or "Interdimensional cat quest" Those were awefull, I'm really sorry hahaha
