Rewritten: Echoes of the Past

I made this mod using an ai platform called Cursor. It did all the coding, I just play-tested and told it what it build and change.

Although I don't think this is what the CurseForge team ment by "Echoes of the Past", I think it is very unique! 
Please comment on the mod if there is anything you think I could improve on, I apreciat it very much!

A RPG themed mod for the 2026 Echoes of the Past ModJam. In your world, an evil Ilager known as The Archivist seeks out power in the history you build. The Archivist is known for wanting to preserve history forever, but thinks the only way to do that, is to steal it. He holds the power of time in a magical artifact called "The Chronosphere".

After playing and building out your world, things start to feel wrong. The next day, something catastrofic happens. You are informed that your world has been reset. You still have your inventory, but your house, your farm, your mines, all gone. Upon closer inspection, you find a mysterious map in your inventory. After following it, you find your self at a red portal...

When you enter, you find echoes of yourself helping in a mysterious dungeon. They show were traps are, how to do a parkor jump, and help fight some monsters.
At the end of the dungeon, you meet face to face with the Archivist. He fights you with strong magic, and some of memories he stoll from you apear to fight with him.

If you are able to defeat him though, you are rewarded with two things. The first being the Chronosphere, letting you rewind time ten seconds, once a day. And the second being, the option to restore your old world, or start fresh.
