Yorna MGS
by yeehaw games

A young mage from a noble family arrives at a distant castle to find it ruined and her sister missing. Will she able to recover lost monster girls and restore the peace with their power? What price will she have to pay?

Ada, the female protagonist, is a prodigal mage with the ability to use monster girl's power as her own. Combine them to create your own play style from a powerful battle-mage to a delicate temptress. Will you overcome your enemies through force or make them into your toys? It's up to you!


Info for v0.1 -> v0.1.5 update


Version 0.1.5 brings the usual content pack: a few new zones with a puzzle, secondary quests, a psycho-parrot pet and 3 core scenes each with 2 variations - normal and lewd. 2 of such scenes are the standard boss and monster scenes and the last one is special. It's a repeatable modular scene. More on this in the features section.

I also updated the “Special Controls” help text both on the Patreon and inside game packages. Now it should be easier to navigate and use.


Interactive non-linear scenes

I made an experiment with H scenes to test out modular and repeatable scene structure for the future. You can check it after getting a maid dress from the dressmaker and accepting baron's offer for work.

This system allows players to try out a new approach with shorter, non-linear H scenes. During the scene, players will have several options to respond and act differently. Depending on the client's character and Ada's sex skills, players will get various rewards - from gold to items.

This is the first step of implementing such scenes with just one client. Later releases will have more poses and sex types, plus more characters and interactive options. Also, I plan to add more frames/pictures to all scenes later, after Yorna achieves the first Patreon goal. As it all depends on player interest, I'll be glad to receive feedback from you.

Shortened Scenes option 

From the 0.1.5 version onwards Yorna supports an additional option for players who want to shorten the length of H scenes in the game. It's available through the main options menu and defaults to "Full" setting. Both "Full" and "Short" versions use the same graphics base and differ only in the text length. You can switch between versions any time you like.

This setting affects both gallery and "on-map" H scenes. All scenes support this feature.

I appreciate your feedback about the feature. Contact me with your thoughts via mail or personal messages.  

Upgrading your castle

Version 0.1.5 brings options to repair your castle and add additional functions to it. To access the upgrade menu, talk to the Adviser Arthur just outside the castle. Minor upgrades are available from your castle's workshop once you've completed the first stage of repair.

At this time, minor features include Ada's personal room with a pet and a herb garden for your alchemical needs. This feature will get more options in the later updates.

Improvements and fixes

Added a cursor image to show the active digit during code input for gallery unlock.

Gallery mode now listens for the Escape key and allows to jump 1 level up in the menu tree up to the main game menu.

Fixed Ada's sex skills info. Now all of them show in proper places in the table.

Crafting materials requirements now follow a clearer notation: materials required - space - slash - space materials in your backpack.

Target window for using food or potions lost the default border setting and is transparent now.

Cleared the cursor in the loot window. It didn't serve a purpose there because there's no choice in the reward collection. You get them all.

Fixed combat background randomization. Now each of three battle backs has exactly 33.3% chance to appear. 

Fixed battle sprites for bosses during in-combat dialogues. They don’t overlap with combat info bar anymore.

Fixed a visual bug with a botched tree in Nymph's forest entrance section.

Updated the Hall of Fame map with a few new names. Also, you can exit the credits section by hitting the Escape key without waiting for the roll-over.

Added short tracks for pianos inside baron's mansion. Yeah, classic music!

Fixed a few minor typos in some descriptions.

Marked logo – loading screen as such to avoid possible confusion during Yorna’s loading.


Info for version v0.1.5 -> v0.2.0


Graphic and scenes

v0.2.0 has 2 new scenes in lewd and normal variations – 4 new unlocks for the gallery. The “maid job” recursive scenes receive 13 new frames with new graphics and 2 new clients with their own character and gifts for the job well done. New frames are focused on Ada working with her hand and happy endings.

As the result, recursive scenes has more variety now. I will add lewd sound to these scenes during the next update – didn’t have the time in this dev cycle.

Monster girls receive their own sprites and mini-cutscenes in the castle. Calista the lamia will receive her unique sprite in the next update and I will try to move from generic stuff towards more specific and original graphics. Yorna v0.2.0 has 2 custscenes: 1 for Leary and another one for Gabby.

You can try out 2 new dresses. One can be crafted after updating you castle to lvl 1, which you could do in the v0.1.5. Check Diana’s shop afterward. The lamia boss has the other one.

Your castle and improvements

Players can upgrade their default “Firepuff” magic skill to a more powerful “Fireblast” in the luxurious Ada’s room. Check the bookshelves on the left.

You can upgrade your garden with a batch of red herbs for alchemy and other crafting needs. Also, I added a well inside the herb garden to gather water. All water gathering yields twice the amount to speed up the gathering process.

Castle receives a default “kitchen/mess hall” zone where you can buy food with a discount. Plus, you can check how well Gabby is behaving while you are gone. After all, the girl has her needs…

Arthur no longer gives the introductory cutscene if the player visited Ada’s room on their own before triggering it.

Crafting and alchemy

Sand tribe’s town offers a book with advanced alchemy recipes. Buying it unlocks new types of more effective potions.

Added materials to monster’s drop list to make crafting easier and more appealing. Reduced crafting cost for some weapons to make them available earlier.

Interface and GUI

Added gold window to the main “on-map” menu. Now you can check you money by hitting the escape anywhere.

Moved status bar under HP and MP bars so players could clearly see the debuff or buff icons.

Removed confirmation on healing items in-combat because Ada is the only correct target for them.

Increased the size of gallery preview pictures so you can clearly see the details. The screen holds 4x3 pictures at the current configuration.

Added scrolling to the gallery mode. To view all the scenes (14) you need to scroll down by pressing the arrow with the mouse pointer or tapping down on the keyboard.

Renamed “Blowjob” to “Oral” as Ada will get opportunities to dive between ladies’ legs too.

Balance & enemies

Placed some monsters further away from entry points so players could away combat if they decide to do so.

Rebalanced the oni so you can beat her easier. She was pretty tough in the v0.1.5 and players had problems with her.

Adjusted skeleton’s movements speed to the usual “aggressive standard”. They were faster than intended.

Losing to monster and bosses now yields less SP. I increased SP for wins to counter this change.

Other changes and improvements

Deleted debug tiles which slipped in during the previous dev cycle. No more cheating :P

Fixed mountain tiles on the global map. Now they are stick together correctly.

Fixed ignored sprite hide command for Ada during one of the dialogues with Arthur.

Fixed some lewd sounds which had a strange panning to the right. Must be a misconfig on my part.

Fixed a bug with the gallery not unlocking the second type of the scene for a specific monster if players already got one type of scene unlocked and had “Skip” as their watched scenes option. Now it works with all the options.

Fixed a bug which blocked the alchemy table in Ada’s room. Now you can brew at home too!

Fixed visual jitter if players attempted to use a pedestal in oni’s puzzle without orbs in their inventory.

Fixed some typos and missing actor tags in dialogs.

The game is a good start, though you should know this is a lot like Melty's Quest that you can find on steam.

I hope you can make it as good as that game.

Really great start!


Awesome game loop:
Collect outfit -> Wear outfit -> See pretty girl in outfit -> Gain SP for outfit via combat or sex -> Learn ability from outfit up max SP -> Collect new outfit.


There's a also a scavenge and craft system as well as monster girl collecting.


Only downside is that as of version 0.1.5, there's only one monster girl and two outfits.


Looking forward to more content! =D

The game crashes when you try to save when playing the mac version, and I have no idea if the other versions also have the same issue. It's quite a major bug so I hope it gets fixed soon.
