We wanted our players to feel immersed inside a beautiful environment but that's not always easy on mobile phones. We used every trick in the book to optimize high resolution art assets for our Ghostbusters firehouse scene. Crunching down poly count and baking every texture we could to ensure a smooth frame rate for the player means less motion sickness and happier customers. Prototyping and testing features quickly with our developers and QA team, ensured the game always felt fun and moved fast. We knew that people would only spend about 5-10 minutes inside our world, so we always wanted to ensure things "felt right." We knew if we could deliver those two things, we'd done our job.
