I'm glad to hear that at least parts of the game are enjoyable to you, and sorry for the ones that aren't, Sadly I reinstalled my PC a while back (My system was randomly crashing) and lost access to the project files in doing so. An auto-run feature would have likely been hard to implement in the old engine regardless!
I probably can't help with the brightness, but pressing alt+enter makes the game full=screen which can help a little on that front!
