Stories are not shaped only by decisions.
Sometimes they are shaped by circumstances.
In this jam, you cannot control the characters directly.
Instead, you control the world around them.
Your game must be a narrative experience where the player influences events only by changing conditions.
The player cannot choose actions or dialogue lines.
Instead, the player can switch states that influence character behavior.
Characters must act on their own according to those states.
time of day
weather
emotional tone
relationship level
environment mood
perspective
memory state
The story should emerge from reactions, not direct choices.
Your project must follow all of these:
No dialogue choices
No branching menus where the player picks what to say or do.
Indirect control only
The player influences the situation, not the decision.
Characters must have behavior logic
They react differently depending on the current state.
Switches must change meaning
Changing a state must affect interpretation or outcome — not just visuals.
There is no hard limit on the number of switches.
But remember the design principle:
Less is better.
Simple systems often produce the most interesting results.
A switch is a variable the player can deliberately change that alters narrative behavior.
turn rain on/off
increase tension
change narrator
move scene to night
alter trust level
selecting dialogue
choosing endings directly
Your submission page must include:
Short description of your switch system
What the player controls
What the characters control
Estimated playtime
Controls explanation
Write character rules, not story routes.
Instead of:
IF player chooses A → scene 5
Think like this:
IF trust low AND night → character lies
Let the story emerge from systems.
Submit:
a playable build or Branchy Studio version

Good luck and happy designing!
We’re excited to see what kinds of stories appear when players control the world.
