A downloadable game for Windows, macOS, and Linux

Erika Yoshino is a slightly introverted college student with a secret: her internship with Marshan Industries is actually a cover for her gig as a magical girl!

But not everything’s rosy - the interdimensional rifts she’s sent to investigate as 'Viking' pump her body full of mana with each enemy she defeats, destroying her metabolism and increasing her appetite.

Can Erika save the city - and her waistline?

FEATURES:

  • A hybrid of Visual Novel/Management Sim and JRPG gameplay!
  • More than half a year of in-game time! Five different dungeons! Calling them ‘unique’ or ‘handcrafted’ is only slightly stretching the truth!
  • Five stages of weight gain and ten stages of inflation!
  • Evolving equipment system! Cast spells from your installed magichip often to unlock more versatile spells!
  • Multiple outfits for Erika to wear at home!
  • Fat girls! Frontal nudity! Stretch marks! Highly suggestive scenes! No explicit sex!
  • Violence that some people may find mildly triggering, a half-assed jumpscare somewhere in here…
  • A small cast of lovable companions!
  • Shady international conglomerates! Corporate intrigue! Insane mad scientists! …Murder?
  • And so much more! (note: not really much more)

---------

Magical Viking Erika was created for Weight Gaming's 2024 'Gain Jam'. This is a slightly more polished release than that version, but still lacking in content despite technically being a "complete" game. 

Please be warned that balance is pretty much non-existent at this state, including for combat, where leveling is slow but your gear generally outpaces enemies anyways, provided you've been exploring.

This game also uses mouse click or touch functionality for some interfaces. Gamepads are supported only if they feature an analog stick and triggers (modern Xbox/PS controllers, etc.) for mouse emulation in these screens.

I'd love to see feedback about what you want from future development of the game!

Due to recent changes surrounding adult content, Magical Viking Erika is completely demonetized on Itch. If you want to support its development, you can visit Open Fly Games on Patreon. Patrons get access to lore dives, development previews, and (soon) exclusive side-stories. There's content even for free members!


Magical Viking Erika is free and always will be. New major versions will be uploaded to Itch on release and not paywalled on Patreon.

Install instructions

Simply unzip the downloaded zip and double-click Magical Girl Erika (Windows/Linux) or Game.app (macOS) in the extracted folder.

Mac users: please note that Apple likes to quarantine files that they haven't signed - for Mac users getting notices that the file is damaged and can't be opened, search for the relevant xattr fix. If you suspect a file may be malicious, always run it through VirusTotal or other malware detection tools first.

Linux users: I coded and tested this game entirely on Linux (I use Arch btw) but if you run into issues (especially Pixi.js complaining about shaders), try running the Windows version under Wine/Proton. It's not ideal, but at least it should work.
