So,  hodgepodgedl recently released a little playable demo for a free-flying, collect-a-thon, diapered dragon game called Super Depravity Quest Shemmy's Quest! Which you can play here:

And sorta commissioned me for some concept art for the characters, I say sorta, since I agreed to help out with designing some newer more cartoonish designs for each of the three current characters he's made, which currently use more semi-realistic designs. From the looks of things, Shemmy here looks like an aquatic dragon.

Unfortunately, there isn't much in the way of a game premise yet, besides diaper dragon collect-a-thon, so I can't really say what the story, or game mechanics are yet. Although it does look like it has some potential from what I've played so far, mainly the movement, flying and swimming feel quite good, but I feel like a stamina meter really isn't needed, or doesn't really make sense with what's currently seen. And I believe more could be improved, such as coins being attracted to you if you get close to them, instead of literally needing to touch them to collect them. And maybe having a reason of adding diapers to the game, Hodge suggested a movement penalty when messy, and maybe even a diaper rash mechanic, which sounds interesting.
