Hey José! If you want some feedback for your existing game project feel free to join our discord and share your game there and ask for feedback or advice.
For the jam, however, we do require that new games be made in order to be submitted! For reference, games with NSFW content is okay for this jam, but we require that the thumbnails + titles for games be SFW and that the title + summary for the game have NSFW or 18+ warnings, as we do have minors that participate.
