I couldn't figure out how to do any of that.This port allows you to both run and play existing LÖVE games and also to create new games directly on your mobile device!
If I open the app, it just shows the no game screen. I couldn't find a way to open an existing .love file.
If I try to open a .love file with the file manager, it says "Unable to open".
EDIT: According to http://www.love2d.org/forums/viewtopic.php?f=11&t=76979 , the way to run a LÖVE game is to copy its files into sdcard/lovegame. I'm not sure exactly what sdcard stands for, I assume it stands for whatever your local storage is named, but it might also work on an actual external SD card too, I'm not sure. This method works, but it's a cumbersome way to run LÖVE games. I expect to be able to open a .love file instead of having to copy the game files into the aforementioned location, overwriting the previous one, every time I want to play a different game.
What about creating games directly on the mobile device? Is there no editing environment provided? Are you expected to use external tools? If so, this ability shouldn't be advertised, unless there is a well-documented way to do it.
All of this should be better documented, since the Android port is now official.
