I've tried the original Life Is Strange twice, and both times I >!failed to save Kate!< because I don't have an infallible memory and quit out of anger.
Reddit style spoilers don't appear to work on Lemmy. Instead use:
::: spoiler description
Spoiler goes here
:::
Which will look like this:

Spoiler goes here
Admittedly, it's not ideal for inline spoilers, but if you really want to hide for the benefit of others, that's they way you're supposed to do it on Lemmy, I guess.
Looks like sync doesn't implement lemmy spoilers correctly, and still uses reddit spoilers. But the lemmy web-ui doesn't honour those spoilers and does them the way I showed in my comment. That's unfortunate, because people using Sync won't be able to effectively hide spoilers, and will potentially be spoiled on things when Lemmy users use spoilers the way the web-ui tells them to in the editor.
