The scene is calm, for now.
CONTEXTUAL ACTIONLead you to the passage
“I haven’t forgotten what you did for my brother. I’ll show you the passage.”
CONTEXT CHANGES THE ENCOUNTER
A meaningful memory changes the relationship and opens up another action.

GOING FURTHER
Before our
first meeting.
Is this just a dialogue interface?
Esyle focuses on character continuity: what they know, their relationship with the player, how they read the situation and the actions they can propose. Dialogue is part of that experience.
Can we start with a single scene?
It’s a good starting point for a concrete use case: one NPC, one event, a few memories and a small set of actions. The demo lets us explore this scope with your team.
What can we evaluate during a demo?
Your scenario, the consistency of reactions, the Unity integration framework and your project’s constraints. Performance, costs and access terms need to be evaluated for your use case.
BRING YOUR NEXT ENCOUNTER TO LIFE
