Playable demo available here.

This pack contains multiple shaders :

* Old School Sprite :
This shader allows you to get the "2D character in a 3D world" effect from early 3D games, without relying on expansive LookAt.
The demo uses it for the goblins, bats, flames and spell effects.
Exists in Lit (no shadows) and Unlit version, both with transparency.

* Animated Texture :
This shader uses spritesheets and displays them frame by frame to create an animated texture.
The demo uses it for the portal and water pool.
Exists in Lit or Unlit, Transparent or Opaque versions.

* Moving Texture :
This shader uses classic textures but will scroll them to create a flowing effect.
The demo uses it for the river and clouds.
Exists in Lit or Unlit, Transparent or Opaque versions.
