I have galleries full of Slightly Damned-related art and other stuff on my art sites:
– deviantArt (also features a Slightly Damned club)
– tumblr

Wednesday Art
From 2015-2018, every Wednesday I would make an illustration relating to Slightly Damned (or my other original comics). I uploaded the images to all my art sites, but this tumblr tag is convenient if you just want to scroll through all of them.

Ask Slightly Damned
From 2016-2017, I drew over 100 comic strips featuring Slightly Damned characters answering questions posed by Patreon patrons. This project is currently on indefinite hiatus.

The Legend of Buwaro: Soprano of Time
This is a parody of one of my favorite video games, The Legend of Zelda: Ocarina of Time, told in comic form with characters from Slightly Damned. You can read it on most of my art sites as well, but the link leads to a page that conveniently has them all in one spot! Started in 2011 and concluded in 2018 after over 150 strips.

Slightly Damned Telegram Stickers

A set of 30+ stickers to be used in the messaging program/app, Telegram! Commissioned by patron Animosulo.

StarForce Media's Radio Play Adaptation
Lead and organized by Eric Shonk, this is an audio adaptation of the story of Slightly Damned, complete with sound effects and set to panels directly from the comic. I hesitate to claim any project that isn't in my direct control "official", but Eric is a pro and a very nice dude, so I'm endorsing this!

(And just because I know people will ask me about it, here's the old, discontinued-in-2010 radio play)
