Recently at University we had a group project. The brief was to relaunch a retro toy for todays market. As a group we decided on Slinky and we all had our own roles. My role was lead game developer. I created the game in Unity and it has been designed specifically to work on a phone, using it's accelerometer to control the slinky as it endlessly goes down randomly generated stairs. Below you can play an adapted version that uses the arrow keys instead of tilting the device.
