Thank you so much! I'm so pleased to hear you enjoyed it. The game is self-contained, but I would like to expand it, though that almost certainly wouldn't be on game boy. Getting this to work on gbstudio was a real chore . I am considering remaking it for the upcoming Panic Playdate using Lua (which would also let me release it for PC) and coding my own 'make your own visual novel' system to do that. I was going to release the 'make your own visual novel' system for free so people could make/port more visual novels to the system.
First I have to learn Lua though.
