A Little to the Left Archipelago

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.
