I wasn’t, but now I am. Looks like version 1.5 should be usable although it might lack rollback. Version 2 seems usable for things like RPGs as long as you don’t enable the history button and don’t show any other buttons on screen during dialogue (because clicking on the screen advances the dialogue, and guess what happens if you click on a button on the screen: it does whatever the button does and then it advances the dialogue too). Until they fix the click handling (and probably add built-in support for rollback), I don’t think Dialogic 2 is ready to be used in VNs, especially if you want those VNs to get shortlisted in the competition aspect of this jam (lacking rollback will be a serious disadvantage, as will the double-handling of clicks on buttons, and while history might sometimes be an acceptable fix for lacking rollback, a history screen that shows lines from previous playthroughs probably won’t cut it).
Another tool, Dialogue Manager might work better than Dialogic 2. But yeah, these are primarily designed for games like RPGs where things like rollback and skipping are less essential.
My own tool does support rollback, skipping and auto, but the only way it can currently play audio is to play animations that play it. And if you add choices you’ll need to make changes to how rollback and history work. I’m not even using my own tool in Spooktober this year, although one of the reasons for that is that its documentation is a bit limited atm and if I’m the one that made it I obviously know how to use every feature including features the documentation doesn’t explain well, so I don’t want to have such an advantage. I do plan on using it in some less competitive jam after this one, and in the process I’ll probably make it easier to use.
