By "it didn't work" you mean that you get the default basic LÖVE 2D screensaver instead of the Cityglitch game when you run the "LOVE for Android" app?
What's directly inside the "lovegame" folder? It should be the contents of the "cityglitch.zip" archive, meaning the folders "cities, data, puzzles, stages, steam, util" and a bunch of .lua files. Also, did you do step 2 properly?
After everything is done and checked, run the "LOVE for Android". If you have opened it before, you have to kill/force stop it.
