Surprise! Not only am I working on this project, but I'm also working on a level editor for it as well! You can learn more about it here: https://johnsterspacegames.itch.io/bfns-plus-ultimate-level-editor.
Also, Joe will not just have missions that you can do, but also jobs, like working in the schoolhouse at night, serving students what they order in the cafeteria, and any others that I come up with.
