I am a writer and game designer, looking to collaborate if you are still looking for a team. At the moment, I have several concepts that would work with the Deeper and Deeper theme, and have started working on one to do it solo if I don't find team members.
Currently, the game is just a Twine virtual novel with choices and a little combat, using a friend's paintings to illustrate the setting and some of the creatures. It follows a goblin named Pogo, who has a variety of gadgets in his arsenal, as he ventures deeper into a magic forest full of Tiki heads and Skull-spiders, tricksy guides and slimy swamps.
