During some of my (too) many <b>Minecraft two weeks phases</b>, I develloped some <b>minecraft mods</b>. Mainly in <b>Fabric</b>,
I even did a <a href="https://blog.ayabusa.dev/2023/10/30/how-minecraft-mods-works-for-dummies/">tutorial to get
started</a> and be introduced to the wonderfull world of <b>Mixins</b> xD.<br/><br/>
<a href="https://modrinth.com/mod/no-more-spire">No more spire</a>: I did this mod for the server that I was playing back then <b>OriginRealms</b>.
Everyone was spamming about the <b>spire update</b> in chat, so I decided to do some <b>cleanup</b> and free the chat from this <b>pollution</b>.<br/><br/>
<a href="https://modrinth.com/mod/modern-chunk-detector">Modern chunk detector</a>: This mod was made for the server <b>9b9t</b> that my friend and I were playing. It <b>highlights</b> the chunk that were
generated in <b>modern version of MC</b>. Great to track bases trails ;)
