Day 6:
So, concerning my goal of "making just as much progress tomorrow"... Unfortunately procrastination has gotten the better of me.
The day started off strong by completing the fifth character, the sea bunny slug. And making his "ears" twitch. 
Other than that, I've been working on setting up my Itch profile, and finally posted my first project!
I've been wanting to get that out of the way for a while now, so I guess this is still progress, even if I didn't add much to the game today.
