"Fixing" this would unfortunately require a lot of code refactoring that I just don't have the time for at the moment and I'm not certain if I'll ever get back to.
During development I took a lot of feedback on the speed of text and tried to balance the pacing of dialogue in the game towards a slower pace to match it's vibes. My play testers liked where I had settled, so whilst the advance text function being a bit wonky was known I didn't think it'd be a big issue.
I'm sorry that this impacted your ability to get far in the game.
If you do want to return to it at some point, I hope you enjoy it <3
