I like the concept of the gameplay- switching between characters with different abilities- and I enjoyed the little bit of that there was once I figured it out.
I liked the character art a lot, both the world sprites and the portraits, but the style of the backdrops didn't really do it for me. The music was good, and the little sound effects added a lot more to the game than one might think.
It's very incomplete as it stands- as a side note I think having characters break the fourth wall and reference that as you did actually worked fairly well here- but I'd really like to see this built upon in the future.
