Coder needed for creation of in-game tutorial

We are ExplorR, a location-based app that aims to gamify the travelling experience. Currently we already have a working prototype, so you will need to spend some time familiarising with our existing software architecture (based on Unity and C#). Once that is done, we need you to optimise the app and work on minor bug fixes. We will need you to create an onboarding tutorial. We will also need you to work on implementing a new game feature - this will be discussed over a call.
