Minecraft Odyssey 1: The Tower of Nigh

A quick run-through of a dungeon I built for my little brother in Minecraft. It was my first foray into redstone contraptions.
The chat commands towards the end demonstrate a magic system I created where some code parses what I say into spells.
For example,
kuga - Ilonggo for "choke". Performs a force choke (levitation and wither effects) on enemies in a radius. It's possible to add a number right after to specify a radius. e.g. kuga 10 will force choke entities in a 10 block radius around me.
