Demo (Public Builds)

Nixie’s Story is a free, hour long adventure with a complete, self-contained story arc.  Explore Mulberry, get transformed, discover The Underworld, conquer The Swamp dungeon, become a Dragon Queen, lay some eggs, and raid the Dragon Temple.

(Story-wise, this corresponds to the first three chapters of the full game.)

This is a fully stand-alone adventure inside The Underworld.

Flash Install Tips:

  • If you don’t already have Flash for your browser, you can install it here.
  • If Flash is no longer supported by your browser, you can download the SWF above and the “Flash Player Projector” for your platform (Windows, Mac, Linux).
    • Note it’s not the obvious ‘get the latest version’ link, you have to scroll down and find ‘Flash Player Projector’ in the list that matches your system.
    • Once downloaded, use windows explorer to drag the SWF onto the projector.
  • You don’t need to install Flash if using the Android APK.

Private Builds contain exclusive content that will never be available in the public build.  Private builds include access to:

  • Additional story chapters only ever available in the full game (including chapters about becoming a milky cowgirl, a stripper catgirl, and a rideable egg-laying dino!). These exclusive chapters include their own new transformations, dungeons, and enemies. There is already a full novel’s worth of content written in these chapters, with more planned on the way.
  • Debug Character Customization Rooms – Instantly level up your character, immediately get plot objects (ie dragon collar, sewer pass, etc), use character transformation items to customize character.
  • Debug Skip – Skip intro text and start with a character who has no tf items (blank slate character).
  • Monster Mods – Create your own monsters to fight using a simple, no-code-required editor.
  • Item Mods – Create items with new functionality powered by custom LUA code.
  • Clothing Mods – Create your own wearable items.  Curses optional.
  • Transformation Mods – Create your own species to be transformed into.
  • Map Mods – Create your own dungeons and game levels using a visual editor.  Set up rooms and place NPCs and monsters exactly where you like them.

Private WIP Builds

For the extra adventurous, private WIP builds are available to high tier backers on Patreon or BMT who are comfortable experiencing content that is not yet complete.

These are work-in-progress builds made in between private builds.  For instance, they might show a chapter with only the first part of the chapter content.  Saving may or may not be disabled for these builds, and they are not as well tested generally.  They will contain sections of untested content, limited/missing instructions, empty rooms, broken text, or halting bugs.

Everything in the WIP builds will later be included in regular Private Build releases.
