No worries. Reaching milestone often helps with feeling better about the self, I think. :)
My personal issue with audio is the volume control. If not careful they become unintended jump-scares.
Are your Twine stories in Harlowe format? I use Sugarcube 2, and in that it’s using CSS-variables, the addClass()/removeClass() to change text/background color, and put the option inside “Settings” section for user.
Vague battle is okay. But I was just confused about the logic of the train of thought right before the final action and then the fantastical element (that had one foreshadow before, but still felt kind of Wha? when it happened). Don’t worry about that unless too many people say it’s too out-of-left-field or something. I don’t trust my own logic on most days. XD
Take care.
