We designed a unique and evocative level select UI in Newton, that I was tasked with implementing. The Prism makes use of Unity 2019's new (at the time!) Particle Forcefields to create a 'singularity' effect, keying the player in to the focus of the game- gravity.
The 'zoom' effect done to transition the player into gameplay isn't just for fun! It helps to imply the delicate nature of the player character, who dies instantly upon touching a spike.
