Although this reply is somewhat late, due to me not hovering around here like I used to, I figured I might as well say it.
In reality, I stopped updating this mod for three reasons: Life, Plagiarism, and Convenience.
On the convenience side of things, I basically had no idea what I was doing. Essentially, I was looking at other people's code to see how they did something, like inventories, and making my own spin on that. There aren't too many tutorials that go in-depth about the more complex Minecraft things -I remember how it took me months to figure out how to properly rotate a block- and I really hated being forced to look at the source code just to do simple things. Since I was still in school, I didn't have much spare time to take Java lessons; and in all honesty, I hate the language anyways. And no, I'm not a C++ advocate. I also hate C++.
Then there was plagiarism. I don't know if it was honestly him/her stealing my ideas or not, but a certain someone who's mod is more popular than mine kept adding features to his mod that I was going to add to mine. That got real old real fast after he added a fish tank.
And then life. About two years before I graduated, I realized that I was wasting my time playing Minecraft instead of more productive things. I had been playing on my favorite server, "Happy Valley", and I was basically the only one there 90% of the time, until one day I remembered what my father said about people he knew wasting their lives on games. I then decided I needed to change, and I swapped over to watching anime as my main hobby. I figured I was better off with something I get tired of more easily than focusing on the more-addictive sandbox game.
And that's pretty much it. I honestly don't think I'll be updating this mod until such a time as I have nothing more productive to do. You may see a 1.24 version, but don't hold your breath.
