Hi! I love Cantata and I've just started reading this too and oh dear am I already hooked! This is probably a stupid question, but is there a way to save your progress in this game? Or have multiple save files?
Well, if you get out of the game, your progress is saved automatically. However, there can be only one save file. So if you plan on doing every route, you'd have to restart from the beginning :))
The IF was made using Twine Chapbook, which is the easiest for people who've never coded before, but it has limited functionality (aka the lack of saves).
