Hey you can actually turn sb3 files to html, there's a website for it (Though I used sb2 to html, might work with sb3.)
Through the static ALPHA || A través de la estática ALFA
A downloadable project
EN: Downloadable file for my game for the Scratch Jam, as the HTML wouldn't work.
ES: Archivo descargable para mi juego de Scratch Jam ya que el HTML no funcionnarí.
To run this, you must have Scratch downloaded on your computer.
