You don't often see a video game specifically designed for a 16-button bespoke controller and for a special one-time party, but that's exactly what Keita Takahashi has done with Tenya Wanya Teens.
Daisywheel divides the alphabet into eight groups of four, assigning each letter to acontroller face button based on the position of the left-analog stick.
Huang showed us a very early (and aesthetically awkward) build of the Arena hub, but all the basic functionality was there, letting us naturally hop into games with the controller's poppy Abutton, and retreat from an app with the back button.
