Just wanted to share a fan mod that I've been helping with called Monika After Story[monikaafterstory.com]. It was started by some folks on ♥♥♥♥♥, but it's grown beyond that to pretty much any DDLC community.
After Story extends the "Space Room" scene with Monika, adds a bunch of new dialogue, and includes a simple chatbot system so Monika doesn't have to do all of the talking. There's more planned for the future, and the project is open to anyone that wants to contribute some new dialogue or help with the game's coding.
*Edit for updates:*
We’ve just dropped a new version of Monika After Story[github.com]. This version is our first to extensively feature new art, including a whole new set of expressions not found in the original game!
The latest release can be found on our releases page[github.com].
New Features for v0.6.0
Monika now has lots of new expressions!
Monika's evening color scheme now better matches her normal sprites for DDLC.
New UI features, including buttons for talking, playing games, and a new music selection screen
Play chess with Monika! (thanks @kadava)
Monika will now ask about your gender and preferred name and address you appropriately
Automatic updating on game start up, or check manually through the settings screen.
DDLC saves can now be imported through settings.
Redid window animation at higher resolution and framerate
New window animation for daytime
Option to turn off animations (greatly reduces system impact)
New events and dialogue.
Monika can now close the game for herself after responding to you saying "Good Night" or "Goodbye"
Help wanted We are really looking for some new artists to help clean up our art and add new poses and expressions to the game. If you are interested, please drop by our development discord[discord.gg] and let us know how you'd like to help out!
