Hey, man. I found this game that features an XP bar, an Iron Golem, a Warden, as well as bells, igloos, and even MODS, which I think is really cool. However, the one thing I didn't like was Steve. They tried to update his texture, but it didn't turn out well, especially when he wears armor. Additionally, Steve's legs look too long in that version. I have an image of Steve that you might be able to use to fix it, but unfortunately, I don't have the ones with armor.

Also, some of the textures in your version are still outdated, like the chest and TNT. I would LOVE to see those get updated. Please make sure to double-check, or even triple-check, the textures. Here's the link to the game, and I hope you find some inspiration from it! It's the Paper Minecraft 1.22 Update by ChessProKing.
(Note: I did not create the game that I linked!)
