Once you've extracted the -zip folder, you need to open the folder in the terminal by right-clicking on it and pressing 'Open in Terminal'. After that you need to type in chmod +x ./TeamTreesLinux.x86_64. As soon as you did that you just need to type in ./TeamTreesLinux.x86_64 te last command will boot the game. After you did this once you can just double click on the application and it should open up.
This only works on Ubuntu. (All ubuntu distributions like mint etc.)
