Overview

Tellephoto (https://nunnyu.itch.io/tellephoto) is a top-down 2D game that combines exploration, combat, and narrative elements. The core gameplay revolves around using a camera to interact with the world, capture spirits, and progress through story-driven levels. The game features a custom animation system, diverse enemy AI behaviors, and a dialogue system that drives the narrative forward.
