You know what they say. If you can't beat it, make your own implementation.

An entity combines a Noun and Actions.

• It can be one Noun
• Noun can be transform ed based on rules that are applied
  • BABA IS YOU -> ROCK IS YOU will give the user control of all ROCK entities
  • ROCK IS FLAG -> all ROCK entities will become FLAG entities
• It can have one or more Actions applied
  • BABA IS YOU horizontally + BABA IS WIN vertically

Text always looks the same and has the same actions.

• It always has the push Action applied
• It always has the same text for the visual
• It cannot be transformed into something else or destroyed
• It can display text corresponding to a Noun, an Action, or a Connector

• BABA
• ROCK
• WALL
• FLAG

• YOU
  • The controllable character
  • If no Noun corresponds to YOU, it's game over
• PUSH
  • The character can move the entity
• STOP
  • The character can not move the entity
  • The character can not move through the entity
• WIN
  • If the character moves onto the WIN entity, level complete
  • If the character is the WIN entity, level complete
• Default
  • By default, the character will not interact with an entity and can move through it

• IS
  • Connects a Noun to an Action to create a rule

A noun plus an action creates a rule.

• A rule has to read Noun-to-Action left-to-right or top-to-bottom (WIN IS FLAG will not work)
• Consequently, the same Noun can be used for two rules
• A rule with IS YOU must exist for the game to continue
• A rule with IS WIN must exist for the level to be complete
