Okay honest guys, this IS just a texture pack but something glitched. I'm on 1.13, after this Enderman was angered by staring in the eyes he lost focus, they do that sometimes and now is glitched, I stare right at his eyes and he isn't getting angry.

Here it is. Lye Batenkaitos from Re:Zero.

This is possible with just resource-packs

Added a boss music resource-pack, the shrimpsnail darkness, will add something for better Endermen Variation, new Ender Dragon model and the end looks already better.

A new concept for the first room! Most of the character sprites are done or almost done, except for a few particularly difficult ones.

I didn't think it can get even better but as you can see it can-

ALIEN GURL DOODLES

This version of Shredder looks badass.

Design 10/10 in my opinion.

You know this ain't some fodder because his eye got scarred so badly and he got out of that fight.

In most cases people don't give detail to non-major characters so what I said works.
