Neo Twiny Jam was a good time to explore and try things quickly, without going into the weeds. And many authors did, often exploring different themes of identity when submitting more than one entry, or trying for different forms of drama.
But Life of Puck and What They Don't Know, may be the pair of entries by the same author that differs most. It's a tribute to the author's pet rat. Rats, like most pets, don't have too much to do, and the author mentions they wrote this to figure out Twine.
It seems like an excellent choice of a self-tutorial, and technically it covers all the bases. Presentation isn't something I generally care much about, but the soft colors and fonts give a homey feel and add to the fun. It reminded me of an idea I had for a Twine game, about two cats I had. (Maybe next year for Neo Twiny Jam.) I'm sure someone else has a dog story. I hope they share it, to help us through the more serious entries.
There are five total endings, though they're not endings in the normal sense. You just have a new day. There are just moments when you've realized you've exhausted one action more or less, and you don't find that there are five until you choose the "take a break" option. I'd found three by the time I had, and at that point, I was able to remember what I hadn't really tried.
You get no special alert when you hit all five, but then again, pet rats aren't particularly goal-oriented. And it doesn't really feel like lawnmowering, just exploring. Also, looping over the same options several times with the same text doesn't feel repetitive, because rats generally don't worry about that sort of thing (okay. They can memorize their ways through a maze. But that's different.)
I'd feel kind of worried if even a pet rat got loose. But here it's a nice game without any real stress. You get out of the cage that is your daily routine as a human, find the five endings, and go back in that cage yourself once you've had an adventure, so to speak.
