A while back i made this
animation of Murky, in a loading animation, from The Binding of Isaac. After the release of Afterbirth+ along with the modding tools for The Binding of Isaac Rebirth, I decided to try adding it into the game and eventually made a small mod, that adds Murky, as a playable character. So, I thought that i might as well upload a notice here.
If anyone might be interested, you can check it out on Steam Workshop, here
Also, here's a pixelated sprite of Brimstone Blitz, i used for the mod.
