It's really hard to help you with code when it isn't easily compilable nor have any of the other suggestions been even considered.
What suggestions have I missed? I added rising edge detection, the ability to press 2nd instead of enter in the menus, improved AI marksmanship and speed, general optimization, improved shop UI, and am working on partial redraw, all by community request. Iím trying my best. If there is anything I missed though, please let me know.
Sorry if this seems rude, it isnít meant to be.
