Support
The most common issue with the app is a loss of position tracking, resulting in the avatar failing to move and/or suddenly jumping. Lillie is the Keeper uses iOS’s AR Kit, which (except on high-end iPad Pros with LiDAR sensors) figures out its location via a combination of motion sensors and camera parallax.
You can minimize tracking losses in a few ways. Play indoors, in a space Make sure you have enough light. Avoid views with large, blank spaces. Repeating patterns (like some carpets) can confuse tracking. (Often, just tossing a sock onto the floor, or something else for it to “see,” can solve this problem.)
If anything else goes wrong (or especially if you find a bug!) please reach out to me at LillieIsTheKeeper@gmail.com.
Background
Lillie is the Keeper is an experimental Myst-like game using AR Kit to create an immersive XR experience on an ordinary iPhone or iPad. It seeks to portray a character with a mental illness as neither a villain nor superhero, with Boston actress Sheri Lee performing much of the heavy lifting in a dual voice-acting role. Visually, it aspires to a heightened, rounded-off realism, pushing the Unity game engine’s Universal Render Pipeline, without demanding top spec hardware or an absurd download size. LitK started life as an honors-graded Master’s thesis at KADK in Copenhagen. It is developed entirely by cinematic & technical artist Matt Rasmussen.
