I'm glad you're enjoying the game, and thanks so much for the kind words! It means a lot to hear that people are having fun with my little creation.
Honestly, at this point I kinda wish I'd just made a game about Lyx and Alice. Maybe they could go on explosive and wholesome adventures in Gramps' van, with Pixie along for the ride. I just enjoy writing their scenes too much ;)
Morgana is certainly in line for a lot of punishment... the Discord server has near-weekly informal meetings where they discuss the best way to make her pay for everything she's done (mostly to Ami) :P
