Ferris Is You is a clone of the awesome game Baba Is You, which is a puzzle game about changing the rules. Go buy it if you're into puzzle game, you won't regret it!

This open-source clone started as a hobby project, to get me into the Rust programming language. So instead of using Baba, it uses Ferris (the unofficial mascot for Rust) as the main character! Out of respect for the original game, I don't plan to release this game with the original levels of Baba Is You.

The project is at the very early stage of its development. It only runs in a terminal, and supports only a limited subset of the words of Baba Is You.

Supported words

• Object names (Ferris, Flag, Rocket, Wall, etc.)
• is (limited support: we don't detect conflicting rules for now)
• you
• win
• stop
• push
• sink
• float
• move
• defeat
• hot/melt
• shift
• open / shut
• and (limited support: only A and B is C, or A is B and C)
• has
• weak
• pull
• tele
• swap
• fall
• on
• near
• facing
• lonely

Not (yet) supported words

• all
• empty
• more
• not
• make (Garden 10)
• word
• up/right (Forest E, 6, 8)

Backlog:

• Core:

• Keep implementing additional words
• Understand and implement contradictory rules settlement
• Find some complex examples (cf TODOs in test files)
• Implement waiting option
• Implement level loader (i.e. build a level from an Unicode description of the level)
• Add tests
• Restructure the code (only one monolithic file as of now)

• Browser version:

• Basic version
• Graphical polish (font, text on 2 lines, emphasize active rules, etc.)
• Level loading
• Saving progress in local storage
• Adding sounds and animations ?
• Level editor

• Unicode version:

• Display orientation of elements (especially needed for move/shift)

Things that will probably never be done

• Support of words "level" and "cursor"
• "Map" levels
• Individual characters ?
