I only ended up using 3 of the ingredients, that's why you don't see Molt. I had a few ideas about how to get it in the game, but I realized that would've added some unnecessary bulk so ultimately I decided to leave it out for a more stream-lined experience. You're right about the interpretation of Echoes. As for the GM-less part, you can play with at minimum 1 player if you want to do a sort-of journaling or idea session thingy (I'm not really into those, but the option is there for those that are). Otherwise, the players can do commentary or make up dumb scenarios happening in the background. You collectively come up with the location and theming (in my playtest, we decided on a lava planet in a coliseum). It's pretty open so you can let your imagination run wild.
The illustration is indeed mine! It took a long time because I don't really practice often, but if it got my ridiculous idea across then I'll take it as a success!
Thanks for taking a look! ^_^
