This is a tutorial based on the A Simple Game game from the original LibGDX wiki. The idea is to demonstrate a small example of how that game could look like in Kotlin using LibKTX which contains Kotlin extensions for LibGDX games and applications.
It should give you a good starting point for developing your own games in the future using LibGDX and Kotlin.
The tutorial will not explain LibGDX or Kotlin basics.
