@Jod wow, really detailed feedback, thank you!
The name change was not intended. I don't want to lie and make a fake excuse, so I'll be honest: Adam is the person Alex is based on. I switched names for privacy et al., but at many times I accidentally started writing his real name because, well, it felt so real. I've corrected it now so that the character is always Alex. I don't really want people I know to come across this :/ (And Steven's my name. I slipped again: Nathan is the character based on me, so the character should always be referred to as Nathan. The whole thing is an indistinct blend of fiction and non-fiction, so I kept mucking up the fictional names.)
Nathan's bi -- i.e. I'm bi. At least that's what people tell me. I've never really understood what I am though, so I try to avoid labels, as I did in the game. But Cassie's not a crush... And her real-life counterpart is a lovely person, so I hope the way I wrote her does her justice. You probably caught the anxiety in shyness in Nathan -- which is exactly what I intended when I wrote it -- and mistook it for a crush.
There's only one ending. On the way there's quite a bit of variation and exploration I'd say -- but everything falls back onto a linear path in the end. I might be changing the ending, however, to make its meaning a bit more obvious/effective. And that will probably involve some music.
And that brings me onto the frustrating problems of audio in Twine... I had horrendous problems with it on my last game. Generally it's very hard to make music play in Twine without a chance of seconds delay, or even a chance of it failing to play completely -- that is, unless the game is played offline. You can maybe get away with one piece here or there, but anything more can be a pain. Plus I ran out of time ;)
Glad you liked the D&D stuff, it was fun to write and hopefully made for a nice mid-game break between the really soppy stuff.
And it's great that you checked out some of the music! I always find it hard to persuade people to listen to it, for reasons you can probably guess. Oh, and Blut Aus Nord and Deathspell Omega are the French Avant-Garde Black Metal Alex jokingly referenced in the game, if you played that part. (There's a few paths for the iPod.)
Last thing, I promise: it's 11,035 words apparently. But some passages are repetitions and variations of others. So in reality I'd cut a couple of thousand words off that figure.
I know I said last thing, but... I'll write a post-mortem at some point, which should explain everything else.
If I haven't said it already, thank you for the detailed feedback! And I loved your game; it is definitely my favourite so far. I included it in a list of my favourite love/lust games in case you didn't see that.
