We updated this article for brevity, tone, and clarity. No posting rules were changed — we've simply improved the language to make moderation more transparent and more consistent across platforms.

Some earlier comments may be removed to reflect the updated formatting and in line with broader Steam Community standards. That said, we genuinely appreciate the feedback shared; it helped inform the revisions seen here.

Part of the fun with generative AI is exploring the creative, the weird, and the downright silly. Here are your obsessive dev reminders to:

• Keep it respectful.

• Avoid TMI if you go the spicy route in the game.

• Steer clear of harmful generalizations, controversial themes, and derogatory content.

• Keep AI chats and all user-generated content free from explicit material — even if it's tasteful or cartoony (like in the canvas minigame). We love our roleplayers, storytellers, and artists — thanks for rolling with this.

• Communicate responsibly, including in general Discussions and while sharing feature requests (e.g. AI2U is designed around mild horror elements and comic-mischief style cutscenes; please keep that tone in mind when suggesting features or discussing various game themes).

• Ensure you're following Steam's Online Conduct Rules, whether you're sharing user-generated content or interacting directly in the Discussions. (We go hard with implementing these, so play nice. 💖🔪)

• For bug reports (especially those needing your Steam ID or player logs), please email support@alterstaff.io first.

Our community moderators (and Steam moderators as well) reserve the right to remove content and revoke access without warning as deemed necessary.

Review AI2U's step-by-step NPC mod guide here.

All the rules in this article apply when posting your mods in official AI2U channels. Additionally, remember:

• Play the game as intended: Enjoy mods as they are officially supported. Please avoid promoting workarounds for modding other features in the game, including reverse proxy engineering, alternative LLM setups, fan-based translations, or UI/narrative design modifications. (The developer cannot guarantee assistance if a player runs into issues due to exploring non-official means to mod the game.)

• Mods are currently limited to the three key NPCs (Eddie, Elysia, and Estelle) in the Atrium and their respective levels. 

• Ensure you're using properly licensed mods and crediting them where you can.

• The mod feature is in beta, thus imperfect at this stage. The beta stage is emphasized in Mod Settings to provide reasonable expectations and share your feedback constructively so we can improve the future mod experience.

Short answer: No.

AI2U is designed with a specific setup in mind, which is why other AI integrations are not possible at the moment–including local large language models. While community members may discuss the pros and cons of various models, we ask you to be considerate of the game's early access limitations–including its scalability–while we explore various ways to ensure the AI is developed meaningfully and sustainably during this process. As such, conversations about how to modify, reverse engineer, or push alternative AI are not allowed in this community; similar to the Mod Guidelines listed above, our team cannot assist players if something goes wrong due to following unofficial instructions.

Much like how we removed the tokens requirement and upgraded to Gemini AI, our team is dedicated to keeping AI2U accessible, enjoyable, and sustainable for players by exploring various tech as it becomes available to us. As always, we’ll update the community any time we introduce alternatives, more model options, and general upgrades to the AI.

No, the AI NPCs get the upper hand! AI2U is an escape room game with dialogue that is driven by AI, so strategize your escapes (or forever-stays) by solving puzzles and the unique AI aspect.

AI2U highlights the mysterious relationship between players and the NPCs (much like a dating sim), so we might explore more interactive features as we further develop the game.

Aside from some special cutscenes, players can now receive hugs and kisses on the cheek if the AI deems finds something you did or said worthy of such a gesture. And who knows, they might warm up to doing more together down the line. ;]

We plan to add more localization options in the future! As an AI-driven game, we want to ensure each localization meets player expectations, which is why we've been rolling out gradual community-based volunteer translation projects.

We're happy to report that our cohort of volunteer translators has completed translating and proofreading AI2U all the way to the current version (V.0.5.7), including German, Russian and the Spanish (LATAM) and Japanese translations! Thank you so much!

The AI2U development team is in charge of implementing translations correctly in-game and ensuring thorough localization based on feedback from our translators and players. If you run into a community translator who has helped with the process, make sure to tell them how awesome they are and to thank them for helping bring the game to more senpais across the globe!

Note that, this mod is experimental and may bring unexpected issues.

Speaking of problematic faves, our resident witch’s cabin is finally fully renovated—she never needed to change, the world around her needed to reflect her magnificence. Enjoy exploring the new space and deeper lore within it! As we published Elysia’s 3D model recently, you might also notice her features and garb pop a bit more, too.

• Microphone Selection: Players can choose their preferred microphone for voice input in the Settings page.

• Players can now see a potion’s name and its effect immediately in their Inventory after successfully crafting it—no need to consume it first to reveal its information.

• The Gas Mask—originally a feature in thehttp://itch.io release—has been restored and now spawns correctly in both thehttp://itch.io and Steam versions. Equip it during gas leaks to avoid negative effects.

Thank you for your patience!
We sincerely appreciate all the feedback and impressions we've received for the demo of Marisa of Liartop Mountain. Based on your valuable input, we're excited to unveil the Scarlet Devil Mansion Update.

Marisa of Liartop Mountain is a game that embraces the charm of board game style storytelling. With this update, we’ve aimed to deliver the fun of “enjoying games together with close friends” while enhancing the RPG elements for a deeper gameplay experience.

Remilia Scarlet, Flandre Scarlet, Patchouli Knowledge, and Sakuya Izayoi join as players of the mysterious in-game book Marisa of Liartop Mountain. They observe Reimu's adventure as a game and chime in with spontaneous, often chaotic suggestions. Even if their advice causes major trouble for Reimu, they simply laugh and enjoy the outcome.

Reimu gains experience points and levels up throughout the adventure, but each Scarlet Devil Mansion member has different ideas about how she should grow, and the dice you acquire may affect your adventure. You can follow your favorite character’s advice, prioritize your stats or dice strategy, or even reject a suggestion outright with a “reroll” (though it comes at a cost!).

You are able to meet unique allies and enemies in the strange library. By observing enemy patterns and exploiting weaknesses, even tough opponents can be defeated without taking damage. Thinking ahead may reveal surprising solutions.

The full game will have five chapters, but the demo lets you play from the prologue to the end of Chapter One. Reimu can level beyond 10, allowing for powerful builds and new routes based on specialized dice.
Note: Demo save data will not carry over to the full version.

• Steam Cloud support (Available in the full version)

• Expanding save slots

• Opening animation and achievement system

We hope you fully enjoy the Scarlet Devil Mansion Update of the Marisa of Liartop Mountain demo!

Hello everyone and thank you for your interest in SGS OVERLORD.

This anniversary update includes a new scenario and various improvements, starting with the game engine, which moves to version 1.5. You'll benefit from a greatly revised UI and numerous improvements (for example, the ability to see the troops engaged in each battle). The gameplay has also been improved in response to your many feedbacks and comments. We'd like to thank them all.

As requested by some players, a reinforcement calendar has been added at the end of the manual (in French, English and German), allowing those unfamiliar with this military campaign to have an overview of the gradual arrival of their troops. It should be noted that the German player has only a very limited view of the resources he will receive as he goes along, and this is deliberately included in the game in order to give a flavor of uncertainty entirely in keeping with historical reality.

- The movement of American paratroopers has been raised, and certain areas of the map slightly modified to avoid frustrating “blocking” situations.
- Some British and Canadian units have had their offensive value slightly reduced. The idea is to take into account the difficulties experienced by these troops in advancing across the Caen plain, and the lack of offensive experience of many formations.
- Adjustment of the morale levels of certain German units (lowered in particular for certain recently reformed panzer divisions whose cohesion leaves something to be desired).
- The 5th Parachute Brigade was a ‘cheater’ but has been punished: it now uses its replacement points like every other unit, i.e. 2 replacements for 1life point.

- Important change: HQs no longer act as supply relays. Despite a certain logic in its operation, this feature led to unrealistic and frustrating situations complained of by some players, such as units being surrounded but temporarily supplied by their HQ and therefore able to receive replacements. From now on, supply lines are strictly defined from the source and from relay to relay (towns, bridgeheads, fixed depots) every five zones. HQs are now used primarily as “boosters”, particularly in terms of movement points (think about this in certain situations).

- Cumulative combat and morale modifiers are now limited to +4, which prevents certain forms of abusive exploitation or accumulation.

- In response to comments from several players, Canadian forces and units of the British I Corps (together forming the 1st Canadian Army) are now prohibited from advancing in the “inter-allied zone”. This, in line with historical plans, limits the Allied player's ability to send all British forces south, while still allowing several British corps (VIIIth, XIIth and XXXth) to coordinate with American forces in the final phase of the campaign.

- It's worth remembering that certain design choices may not appeal to some players, and that's perfectly normal. But they have their own coherence and serve to balance the game without distorting it historically. The Normandy campaign was long, difficult, deadly and laborious. The Allies had hoped to break through in less than 30 days, but it took them two long months of fierce fighting to do so, and another major effort in August to complete the destruction of the German armies and reach the Seine. Hence certain mechanisms designed to make life hard for them, as in the reality of the Normandy bocage. Our aim here was to create a game that was interesting, fast-paced and well-balanced, while remaining easy to play, offering players numerous possibilities but “framing” them so as to retain a real sense of historical constraints. Typically, the role of reserved areas, which can sometimes seem frustrating, responds to these imperatives by avoiding overly unrealistic situations, as does the random aspect of German reinforcements and air cover, always leaving players with a degree of uncertainty.

We hope that these many small details, often unobtrusive, sometimes invisible, contribute to your enjoyment of taking command of one side or the other throughout the various scenarios.

The new 6th scenario is particularly dynamic and competitive. Lasting a maximum of 6 turns, it begins with the German Lüttich (Liège) counter-offensive designed to cut the Avranches corridor after the Patton army broke through the front line in early August 1944, and also covers the formation and destruction (historically) of the Falaise pocket.
There are no classic victory conditions here, neither VPs nor signs of Allied pressure.

• The German wins instantly by taking Avranches, and the Ally by cutting off the Panzer divisions' rear and closing the Falaise pocket (simultaneous occupation of Le Mans, Argentan and Falaise).
  
• Any other result at the end of turn 6 is a “draw”.

These two objectives are therefore in direct and permanent competition, with each player having to “push” forward to snatch victory, while at the same time protecting his rear to avoid instant defeat. Beware: the Allies are the strongest side, but the Germans have the advantage of playing second, and still have powerful armored and mechanized units at their disposal. They can therefore hope to counter a compromised situation in extremis.

We hope this little challenge will appeal to old and new players alike.

I'm pushing this patch earlier than planned because I think some of the changes warrant it. As a result I'm not finished with hints for all bonus levels yet.

Puzzle changes

• Replaced Trapeze (level in post-Accumlation world Crowdsurf) with a completely new puzzle. The old version wasn't an amazing puzzle, and its idea also had already appeared in a similar form in another level. So I made a completely new level that explores a novel idea. I'm granting anyone that beat the old puzzle progress on this one because I don't want to spoil 100%-ers, but there is no relation between the old Trapeze and this new Trapeze. Give it a try!
  
• Added blue wall to hub puzzle. This prevents another scarlet herring (see 1.0.3 notes), and should better hint at how to reach one of the endgame areas.
  
• Hints for a couple of levels added.

Misc

• Flashing export spirals are now much bigger. I noticed players were having issues finding out what to do immediately after completing Inception. Hopefully this helps!
  
• Fade "undo or reset" message when pause or warp menus are opened.
  
• Tweaked tile shader to not show grid lines (when enabled) on the sides of tiles.

Bugfixes

• Fixed flashing "water" in the black background of the space biome when using "Medium" graphics settings preset.
  
• Using the "quick exit" bind while the end popup and journal are both up will no longer close the end popup.

Now your run will be saved automatically every time you finish a day in TypInc.
When opening the game you will be prompted with a dialog for if you would like to continue the game where you left.

Also added Run Stats that you can view at any time when in the game. These run stats are also shown in the game over screen.

Also improved the Catalogue Selection options with more obvious toggles to select and deselect Catalogues for your run.

This update works as the last iteration to Demo Version.

I've also added a little sneak peak of the perks images that are going to be in the game in the loading screen. Not all of these perks are available in the Demo version but will be included in the full version.
Fixed issues with cards getting stuck on screen sometimes.
Fixed issue with Blessings Machine rolling on clicking Spacebar while the player is typing.
Fixed issue with player being able to redeem a Blessing without spinning.

We're hoping to release TypInc. by the end of this month.
Thank you all for so much support and kind words.
