Hi there, I'm glad you enjoyed playing Belong (all the routes too!) and thank you for the support <3
You got it! I basically just thought of ways for the letters to represent the characters ('bel' representing Carpiana's smiley face, 'on' representing Dylan's butterfly transformation and 'g' as tape measurement for Flint's handy works/nature) rather than linking the letters with significant meanings behind them. Hope it clarifies~
