iPhone & iPad
Three classic adventures in one collection, with touch controls, a custom interface and integrated guides.
I developed the collection interface and game selection, integrated the existing ScummVM GOB engine, adapted the controls for iPhone and iPad, and added in-app guides. The original games remain the work of their creators.
iPhone & iPad
A woodland puzzle game about guiding a little crowd to safety with bridges, tunnels and other abilities.
From the initial concept and game mechanics to the visual direction, graphic design and programming in Swift, SwiftUI and SpriteKit. I developed the gameplay logic, levels, controls, interface and progress saving, and prepared the app for iPhone and iPad along with the App Store materials.
Development
