Thanks so much for playing! I'm glad you enjoyed the story.
Madoka Magica was definitely a big influence, along with Yuki Yuna is a Hero and Sailor Moon. The Persona game series is also a pretty big inspiration for these.
I'm intending to eventually release a series of longer games that will reveal much more of the world and lore than I can fit into Jam-sized games. However, there are currently 4 other Jam-sized games in this series on my main page. Of those, June Mejos and the Moonlit Curse probably has the most backstory/lore in it.
