Oh yes, it seems that there is at least one Choicescript game in the Neo Twiny Jam.
It's another game dealing with the theme of existence. An unknown being creates you, a human(?), and tries to learn more about being human from you. There are a good bit of choices in the game, with some changes to the text depending on your choice, but the game's structure is linear as a whole. There's a stat page as well, but you probably won't have to use it.
It's good for a short and entertaining read. You might even want to replay it to try out the different options.
