This project is an effort towards a 2D building game which aims to mix Terraria/Starbound style procedurally generated and modifiable terrain grids with player-built structures and vehicles as in games like Space Engineers or Airships: Conquer the Skies.

This would allow the player to build cars, airships, submarines, space ships, or multipurpose vessels. All structures and vehicles created by the player will be irregular grids created out of 2D tiles/blocks.
