Hospital? Aiyo! I hope you feel better soon!
Ah, so I will just have to click through, that's fine. It's not 'skipping' I want but the auto-forward, meaning that each line of dialogue or narration will appear by itself after a set time (so, in Ren'py, you had it right initially - and I can definitely believe it's buggy). Too bad though, it appears to be a very good VN system otherwise... and Unity seems to randomly decide to crash games for no reason - is there no good option for a program (sad sigh)?
And as for your new game... of course I'm watching - always following. It's been a joy to see the progress from the earlier games to now (everything keeps getting better).
