Hello. Yes, indeed, I meant the shoulder buttons... I have no idea why I wrote trigger.

Ah, finally someone got that bug. I thought it was an issue with my hardware. Sometimes you'll have to press two buttons simultaneously in order to go to the next stage. It seems it only happens on the controller. I'll try to fix it once I revise the controller support (it was added just this build so it's very WIP. Same applies to the sword attack). As for advancing the dialogue, you should be able to do it with the A button. If it's not working, then it's another thing I need to fix. Anyway, thank you kindly for the report.
