No-game screen should give (brief) instructions
In the last 2 weeks we've had 3 different people asking "I installed and run LÖVE but I can only see the rubber piggie, what do I do?"
For the next version of LÖVE, I recommend adding a small text explaining what is happening somewhere in the no-game screen.
It doesn't have to be big or extensive. I propose this:
Hello! This is LÖVE's "no-game" screen. You are seeing it because LÖVE could not find a game. See https://love2d.org/wiki/Getting_Started for details.
