This is a cute little choose your own adventure! Nice work and I hope you do more Decker things in future!
As a Decker tip, if you set the field widgets to "locked" in the widget menu, that'll mean people can't type in them when they're playing - it can give things a more polished feel if that's what you want. Also, if you use the File->Properties menu option you can save the deck out in a "locked" format where the menu bar doesn't show, which gives it more of a stand-alone game feeling.
Stop!! Hibari-Kun!! is a series I've heard of a fair bit but haven't checked out myself yet - I probably should give it a try, huh?
