I have created the first sprite. Here's Boopkins(Alphys). This is my first sprite so it may not look that good. I will try to make a better one for the full game.

I finished the Battle Sprites

Another Sprite. This time Luigi(Toriel).

Parchment Sprite 1

Here are the main sprites so far

Overworld Sprites

Note: This is not an official sprite. This is meant only to show the character's design.

Extraordinary Sans

I finally finished Purgatory's overworld sprites

I got the main sprites for Sans done

I made this in Stickmin Creator. I am pretty proud of it.
