ZDoom

Inspired by a single gif from the Spriting Carnival, this'll be an attempt at a mod where you raise your own demons.

Currently, there's no actual play to it, but I do have a hud element that lets you watch a random demon wiggle around on your screen.

Currently there's only a cacodemon, demon, and revenant, and which one you're assigned is random upon starting up a map ( you don't keep it between maps ). Both of these will likely be changed upon deciding what direction to take this, but for now enjoy a hud elemental that'll hopefully endear itself to you.

This idea remember me of this old Skulltag mod.

How about using CVARs to make it persistent, and feed it things like ammo, armor, powerups and such? Maybe make it give you bonuses if you do enough of task X with it?
Or making monsters give you chunks when they die, and you can feed those chunks to your pet?

I instinctively read the ttitle as Demonpachi

Sounds like a fun mod all the same!

hope it goes trough, this sound cute and fun
