Lacrima thank you for the post 
Just an FYI the devs are working to cleanup and close existing bugs before they consider new code. I haven't checked to see if anything is sketched out for Quadruple Attack yet. I do know the focus of the project is Rise of the Zilart and before with everything else being worked on either by less active/experienced developers like myself or possibly yourself until they feel they have reached there milestone.
Just want to set your expectations so you're not like WTF mate I told you about this X months ago...
