Paper2Galgame August Update: Custom APIs, Multiplayer, Free Reading,More Galgame

Hi everyone, this is the Paper2Gal team.

It has been less than a month since Paper2Galgame officially launched on August 10, but honestly, it feels much longer than that.

Over the past few weeks, we have been reading feedback from Steam reviews, the community, Discord, Bilibili, and many other channels while continuously fixing bugs, reworking parts of the experience, and adding new features. Many of the updates released in August came directly from player suggestions.

If you only tried Paper2Galgame around launch, opening it again now should feel noticeably different.

Here are some of the major updates we completed this month.

Custom APIs and Character Features

Custom API support is now available again.

Players can configure compatible model services in Settings and use their own APIs or other supported models for story generation.

We have also improved several character-related features:

• Adjust character position and size

• Preview characters while creating or editing them

• Preview character voices

• Keep the currently selected character after restarting the game

• Added JPG support for character images

• Fixed multiple Workshop-related character display issues

• Improved character resource saving and migration

Multiplayer Mode

Steam multiplayer was added in August.

The host can create a room and invite Steam friends to experience the story together.

Before the session starts, the game synchronizes:

• Characters

• Character artwork

• VRM models

• Voice resources

• Backgrounds

The story begins once everyone has finished loading.

During multiplayer sessions:

• All players can vote on story choices

• The option with the most votes becomes the final choice

• Ties are resolved randomly

• When the host asks a question, everyone can see both the question and the answer

• Voice chat is supported

• Players can use emotes

• Workshop emote packs are supported

• Steam names and avatars are displayed

In short, you can now read papers together inside Paper2Gal.

Free Reading and Paper Q&A

In addition to the original story-based reading mode, Paper2Gal now includes continuous paper Q&A.

Players can ask follow-up questions about the whole paper or the current section and review previous conversations at any time.

Answers use the paper text, section structure, and extracted images as context, with the goal of staying closely grounded in the source material.

The Raise Hand feature has also been improved:

• Steam players can use Raise Hand up to 30 times per day

• Follow-up questions are supported

• Fixed cases where custom forms of address did not work correctly

• Improved grounding between answers and the original paper

Paper Reading and Story Generation

A major focus in August was improving paper parsing and story generation quality.

Changes include:

• Improved table of contents and section recognition

• Stronger grounding between generated stories and the original paper

• Reduced off-topic and unrelated story content

• Improved mathematical formulas and LaTeX rendering

• Improved long-document parsing

• Improved generation failure handling and loading behavior

• Failed story generation no longer consumes the corresponding usage count

• Failed questions no longer consume usage

Paper introductions now try to explain the content step by step, covering:

• Research background

• Core methods

• Experimental results

• Main conclusions

The system can also recognize figures such as data charts and architecture diagrams and use them to support explanations during the story.

Images on the blackboard can now be clicked to view them at a larger size.

Steam Workshop

We continued improving Steam Workshop throughout August.

Players can currently share and subscribe to:

• Characters

• Backgrounds

• Emote packs

• Community language packs

We also improved character uploads, updates, resource caching, and subscription behavior, while fixing a number of Workshop-related issues.

Our long-term goal is to gradually turn the Workshop into a MOD platform for both characters and learning content.

Voice, Music, and Localization

Custom voice support now includes GPT-SoVITS v2 API compatibility.

Music now supports importing multiple MP3 files at once, and audio preview behavior has been improved so different audio sources no longer overlap unnecessarily.

Community language packs are also available.

Players can now:

• Export translation templates

• Create custom language packs

• Import language packs

• Share them through Steam Workshop

• Automatically receive updates for subscribed language packs

We have also continued improving the Simplified Chinese, English, Japanese, and Russian UI text.

Save Data and Loading Improvements

We made several improvements to saves and loading:

• Steam local saves no longer have a fixed limit

• Save files can be renamed

• Improved Steam Cloud synchronization

• Improved migration of older saves and character resources

• Save management now prioritizes lightweight summaries

• Steam Cloud reconciliation now runs in the background

• Added list caching

• Added new loading placeholders to save management, backgrounds, Workshop, and paper loading pages

The goal is to reduce unnecessary waiting and repeated loading.

Other Changes

We also made a number of smaller usability and stability improvements:

• Mouse wheel support for advancing and going back through dialogue

• Improved movement and jumping in the parkour minigame

• Fixed cases where the parkour floor failed to load

• Added fullscreen mode

• Press Esc to exit fullscreen

• Updated the in-game cursor

• Improved sharing posters and result screens

• Fixed several Steam achievement issues

• Fixed overlapping buttons in the character editor

• Improved the first-launch experience

• Fixed UI issues on the language selection page

• Improved voice, vision model, and generation stability

• Updated the privacy policy and terms of service pages

What’s Next

Most of August was focused on fixing launch issues and completing the foundation of Paper2Gal.

In September, we plan to make a more noticeable visual and interaction upgrade, along with additional updates around the back-to-school season.

Our next priorities include:

• Better document parsing

• More stable AI generation

• Better reading and Q&A interactions

• Improved character presentation

• Further Workshop improvements

• Overall UI and visual upgrades

Thank you to everyone who has continued sending feedback during Early Access.

Many of the features already added to the game came directly from player suggestions.

See you in September.
