About Girl Genius: Adventures In Castle Heterodyne
Girl Genius: Adventures In Castle Heterodyne is an action-adventure where you play as Agatha reclaiming her ancestral home from a mad AI while crafting gadgets, commanding minions, and rebuilding traps to solve puzzles and defeat enemies. Dive into the award-winning gaslamp fantasy world of Girl Genius with romance, mad science, and the chance to stand against an empire as a true Heterodyne heir.

ACTION, RRRRRROMANCE (pronounced like Provence) and MAD SCIENCE!
Discover the award winning, gaslamp fantasy world of “Girl Genius™”! Experience Agatha Heterodyne’s story, as she navigates the hostile hallways, catacombs and kitchens of her ancestral home, Castle Heterodyne.
As the Lost Heir to a mad family, she must return the ancient fortress to its former glory and ascend the throne as a "True Heterodyne". Only then can she stand up to the might of the Wulfenbach Empire and other power hungry usurpers. But first, she has to contend with a corrupted and insane AI controlling the castle, its spiky death traps, and bottomless doom-pits. Not to mention the painfully pink cherry on top, Zola Heterodyne. Another lost child? Or just another villain here to steal your thunder.
Time to find out.

- Build tools like the Grapple Gun and the Wrencherang at the Workbench, and use your tools to explore and solve the castle’s challenges.
- Discover numerous sights and secrets, by being perceptive and using your tools to the fullest.
- Defeat foes in furious melee combat or with explosive gadgets, and utilize the environment to your advantage using your tools.
- Use your trusty Dingbot minion to explore places Agatha can’t reach, by moving in tight spaces, digging beneath or soaring above danger.
- Use the Dingbot to solve lock puzzles, and operate the internal machinery of the castle.
- As Agatha’s power over the castle grows, command the castle AI to release traps at your foes, and activate mechanisms.
- Use the unique “Build System”, rebuilding scrap traps into objects like the Springclank, Grappleclank and the special Rollerclank, giving the player a suite of tools for creative spatial puzzle solving.

Recent verbatim reviews from Steam — separate from playze.io community reviews below.
Girl Genius: Adventures In Castle Heterodyne is a fan-made action-adventure that successfully captures the spirit and lore of the beloved webcomic, with engaging puzzle-solving, exploration, and a satisfying story set in Castle Heterodyne. Players praise the faithful world-building, responsive gameplay, and clever mechanics, though opinions split on the difficulty and combat system, with some finding the challenge rewarding while others feel the combat is repetitive and the overall scope feels limited.
I bought this game primarily to throw some money in the general direction of the Foglios, whose web comic I've enjoyed for like 20 years now. The game retells the part of the story where Agatha retakes Castle Heterodyne, lovingly rendered in 3D. The gameplay is at best, perfectly adequate, as long as you don't make the mistake of playing on the Hard difficulty.3 found this helpful
Developed and published by Rain Games, Girl Genius: Adventures In Castle Heterodyne is an action-adventure title that successfully transforms the beloved Girl Genius comic universe into an engaging interactive experience. Drawing inspiration from the award-winning graphic novel series, the game blends exploration, puzzle-solving, platforming, combat, and storytelling within a world overflowing with eccentric inventions, steampunk technology, and imaginative science-fiction concepts. Rather than feeling like a simple adaptation, it captures the spirit of the source material while delivering a satisfying adventure capable of standing on its own merits. The story centers on Agatha Heterodyne, a brilliant young inventor who discovers her connection to one of the most powerful and notorious families in the world. Her journey takes her to Castle Heterodyne, an enormous mechanical fortress filled with secrets, dangerous experiments, hidden passages, and malfunctioning systems. What begins as a quest to reclaim her heritage gradually evolves into a larger struggle involving rival factions, ancient mysteries, and the unpredictable intelligence that resides within the castle itself.

Adventure, Romance, Mad Science! This game has it all! A Stunning look inside the Infamous Castle Heterodyne from the Girl Genius web comic with great care taken for the story's lore. I felt I was in the middle of the lost chapter of the story. Responsive game play with adequate forewarning of new mechanics and plenty of optional secrets to find. I always felt that the failures were on me (although the default camera could stand to be a bit less murdery, but what do you really expect from Castle Heterodyne). A stunning conclusion to the Heterodyne Boys and the Mystery of the Vanishing Game Developer series.1 found this helpful
This is super fun. Lots of clever things to figure out, exactly like I would expect from this castle. Fantastic little guys trying to kill you all the time, having to use actual mechanics to get through to the next area. Challenging, but I didn't die nearly as much as I normally do. Seems like most of the negative reviews dislike it for exactly those reasons. Maybe it's just not the type of game for them, you know? This was a game for having fun, and not everyone is into that.1 found this helpful

This is a fan game with lots of love but not enough production value. The setting is great, the comic it's based on is great, the art is great, the puzzles are okay at best, the main gimmick of cubes that you transform is good but there aren't enough of them, you could have ten times the puzzles, the combat is bad and repetitive, the boss fights are actually good and challenging (they were hard for me on hard mode, though ultimately doable), but there are very few of them, the castle feels, ultimately, too small, and yet there are annoying loading times all the time, the character models are atrocious, you can barely tell them apart, they look like wii avatars, sheesh, also there's barely any interactions, although they do try to be faithful to the comic, bless their hearts, and there are silly grinding achievements that took too long after I beat the final boss. All in all it's a solid effort that ultimately falls short. I give it two out of four hats and that's just barely.
