Hello! Here are the Unity project files for the latest video. In case you missed it, the video is out over here :)
For anyone interested in actually playing the game (although it's really not much of a game at the moment), the controls are as follows: Turn the plane using the A/D keys. Press 1, 2, or 3 to select the country/city you want to deliver to. Once you've arrived, press spacebar to drop the package. You can then press spacebar again to generate another set of three countries/cities to choose from.
Thanks so much to all of you for the support, and please let me know if you have any questions about the project!
Edit: It seems I ran into a size limit issue on here and the files didn't upload, sorry about that! To work around it, I've had to split the project into three files. The first is the project itself, followed by two zips containing the height map tiles (north and south hemisphere). These need to be unzipped and added to the Assets/Data/Height/HeightTiles folder in the project. Then select all the textures and apply the settings as shown in the attached image. Finally, in case Unity doesn't notice the images have been added, you may need to manually add them to the "Tiles" texture array on the World object. Sorry for the extra steps!
For the 3d models (ship and airplane) to show, you'll need to have Blender installed (free from blender.org)
Edit 2: I've uploaded a test build of the project for windows if you just want to try playing it. You can find that here.
