Dummy Bird

Windows:

Extract the zip file where you want to install it, and that's it. Double click dummy-bird.exe to start the game

Android:

Download the apk file on your phone, use a file manager/explorer (eg: X-plorer) to do to the download folder and open and install the apk file (it might trigger a warning as is not in the official store)

Linux:

Extract the .tar.bz2 file where you want to install it, and then to run it use the terminal to go to that folder and run the line:     ./love dummy-bird.love

If you already have Löve (11.x) installed you can just run it by double clicking the dummy-bird.love  file or in the command line by love dummy-bird.love. In this case the love file won't be needed, you can delete it.
