Well, I'm just expressing my personal opinion. Perhaps others feel differently. Personally, I have no issue working with the limitation of controlling two characters/objects independently as the design constraint. I actually have a few interesting ideas. I was just trying to make the point that such a limitation is not inherent in the control scheme.
I really hope you continue with the jam, but since it seems my contributions are not very helpful, I'll be bowing out of participating to avoid any further misunderstanding.
Good luck with the jam and I look forward to playing all the submissions :)
