So! It completely slipped my mind that the artists that made some of the placeholder sprites would probably want credit so:

Toriel gatekeeper sprite was by PooStablook on Deviant Art (https://www.deviantart.com/pootstablook/art/Deltatale-Toriel-771626589)

Sans deltarune battle sprite was by IStorySwapCharaI on D.A once again.

Kris battle sprite was Puzzleheaded_Base_35 on reddit

Kris shield sprite (with fighting sprite) was by Kiptty on Reddit

I will not be credditing the Asgore Deltarune sprite after the owners actions, nor will i be credditing the Alphys sprite.

That's all the ones that werent anon.

(I'll be posting this on all my games but with dif credits)
