making interactive fiction for e-readers with tweeul8r
2026-06-04
earlier this year i wrote a game for casio calculators, and shared the tool i made for converting twine stories into BASIC: tweeul8r. now i've extended that tool so it can also export stories as static HTML - which in turn allows them to be converted into ebooks!
here's what WINDING DOWN looks like on my 16-year-old kindle 2:
if you want to play WINDING DOWN on your e-reader, you can download the .EPUB or .MOBI files from itch.io :)
if you want to make your own ebook interactive fiction using tweeul8r, first you'll need to write a story using twine and export it as a TWEE file. then you'll need to copy the twee source into tweeul8r and export the game as static HTML (i found the multi-file version works best for ebooks). lastly you'll need an ebook converter program to turn the HTML pages into an EPUB or MOBI file: calibre comes with a command line tool which is what i used - just point it at your game's index.html and it can find all the other pages by following links. (note: to get ebook-convert to find all my game's pages i also had to increase the allowed depth of recursion using the --max-levels flag)
p.s. if you make anything with tweeul8r, please let me know! (you can email me by clicking the reply link on this post)
