If you would rather not make a video due to problems with google etc,
you could just record your gameplay as demo file that anyone else could
playback as long as they have the same version of winrottgl:
Run winrottgl
from the main window, go to 'settings' then 'general'
from this window, you can set how much memory the demo should use,
note that when you change the memory, the window beside it, will
update the minutes the demo should play, here's some other
commands:
Alt+R to start recording
Alt+E to end recording
Alt+D to demo playback
You then zip (or rar) if you wish your demo file, and post it where other
people can download it. This process sidesteps having to make a actual
video file.
