It's clear that you wanted to design a battle system like The World Ends With You, which I want to give kudos for. It's a really unique idea that can be really rewarding, especially using two different input methods.
The design does fall kind of short however. It was almost impossible for me to coordinate both characters at one, especially when positioning both of them is so important that they always need attention. It would have been interesting if you made the keyboard character more stationary, so you could pay a little less attention to that side.
Kudos on the idea, but feels like you just quite did not make it during the jam. Please, feel free to explore this concept outside the jam!
