This game is Great, I really hope someday I could do something like this. I am sorry I can´t donate to this came because it deserves it. I would even pay to play it on steam
Whether you mean kill your boyfriend or make a visual novel, I agree. If you'd like to do the visual novel part renpy or kocho are pretty good, and free programs. You can commission an artist for sprites or do it yourself. Now if you'd like to do the killing your bf part, grab a knife. Hope this helps
