Nice demo!! (I'll write a bit more now O__O)

I like all the characters and I really think the art style of colored backgrounds but sprites that are more of sketches looks interesting  (EDIT #3: I don't think it'll look like that in the full game...I think the colored in sprites will look even better!). In fact, the whole game looks extremely polished and well-done. The characters are unique, have their own voice,  and the dual protagonist angle is super intriguing, and novel to me honestly. 

Good luck on the finished game, too. I'll try to play it if I'm able to lol.
