About this mod Author’s original text
A Little to the Left Archipelago
An Archipelago multiworld randomizer for
A Little to the Left (Steam,
Windows).
Your run is a track of puzzles, many of them procedurally generated. Its
solutions, the groups you tidy and the credits are checks; Puzzle Packs, the
game's mechanics (Stacking, Rotating, Drawer and the rest), Skips and Hint
Pages are items, and any player in the multiworld can be the one holding
yours.
You also need
- A multiworld to join. Whoever generates the seed needs alttl.apworld, and
every player a yaml; both are on the
GitHub releases page.
Use the release with the same version as this mod.
- The base game on Steam. Both DLCs are supported and off by default.
Install
- In r2modman or Mod Manager, choose A Little to the Left and
select or create a profile.
- Install this mod (Install with Mod Manager above, or search the
Online tab for A Little to the Left Archipelago and press
Download). BepInEx comes with it as a dependency.
- Press Start modded. The first launch is slow while BepInEx generates its
files. The main menu gains an Archipelago entry.
The mod manager shows the version it installed: take the alttl.apworld and
yaml from the GitHub release with that same version.
Connect
The main menu gains an Archipelago entry. Fill in the server (host:port
from the room page), your slot name exactly as in your yaml, and the password
if the room has one, then press Connect. With Auto-connect on, the game
rejoins your multiworld every launch.
A randomized run keeps its own save: your campaign save is never written to.

Install & use Install: follow the bundled instructions
- Unzip the archive from playbuff and read the bundled readme / instructions first.
- Most mods rely on the game's mod loader — the usual route is a community mod manager (such as r2modman): pick this game, install, and it handles the loader and dependencies.
- For a manual install, put the mod files into the matching Mod / plugins folder inside the game directory.
- Launch the game to confirm it loaded; mods with listed dependencies need those installed as well.
Install locations vary a lot between mods — the bundled readme is the most reliable guide.
