I had wanted to add animations to my first update but I put it off to see the response I'd get on my hand drawn art or if there was any problems with the characters. But then I got thinking I might be waiting a long time to get a reply.

So now, I've started a new Unity Project  using 2020.3.6f1 and I'll be reanimating all of the characters using the sprites I uploaded in the initial pack. BTW, I named all of the parts (character_legR, characterHead, etc.)

Here's a list of animations:
idle
move / run
hit
death
attack [for Fire Demon, Floating Eye and Horned Crab characters]

I won't be adding gun animations as I'm going to leave that up to you.

Sorting Layers for most characters

Body SL1
Head  SL2
Legs SL 0

War Pig "Player"

Hopefully I set this up. I'm not animating an attack or gun movement. Feel free to add those animations and your own FX.
