This week I couldn't help but feel that I should do a little more planning for the next stages of Ball Butler. These plans have taken some time to put together, but I've already found a few problems that I undoubtedly would've run into later if I hadn't done this planning now.
This likely won't be the most entertaining stream, but I believe this is work that had to be done, and I think it will hopefully mean that future development goes much more smoothly than what I'm used to.
