Yo this is a fun concept, and with a little more fleshing out it could become something incredibly cool! Drawing the imaginary definitely is a nice touch. I think this game especially though needs a sample adventure for me to fully wrap my head around the vibes. Still, great work! 

first of all....adorable. include art in your character building is so fun! The Challenge track is a little bit confusing at first, but it's not bad. Some examples for the GM to run the game would be cool, too!
