I have just (re)published my first mod on this website. (I published it previously when my website was hosted by Godaddy using their horrible Website Builder service. Now I’m used to WordPress I won’t be looking back!)
The mod is called Highway Maker. It allows the player to put high speed highways in their Minecraft world while playing a survival game. Unfortunately it only runs on MC 1.11, because I finished it quite some time ago and got distracted when MC 1.12 came out with functions.
