Hi, I'd like to especially focus on its menu and html/css-parts (generally also for other game-collaborations), while I like your focus on choice-based types which are similar to games that I prefer in coding too.
I've never heard of Snowman 2, but maybe read of Twine, personally I'm starting from eithera blank page to add what structure fits in or am I having in mind how visuals should look like but as they're affected by browser & used devices anyway e.g. mobiles refer to hovering or doubleclicks differently than if using a laptop.
I could preview it on windows but noncellphones, so just a laptop which works best if just coding textbased-bit to prevent lagging still getting rid of or adjusting options, adding more or narrowing them into sections/dropdown, etc.
"effects" like as:
shadows or text fades its colours
border-radius, colour & style
text's style (font type) to up bold, italic, if hovered or leftclicked instead (or double to tripleclick)
switching as replacing innerHTML
also others that aren't included above...
