How can something so simple be so difficult? This question can apply to both playing Batman on the NES and uploading a Batman review onto YouTube.
For any number of reasons, it required no less than 10 attempts at rendering and a separate three tries at actually uploading the video. All in all, I think I spent more time watching scrolling bars than the time it took to develop the game.
Good news: the review is up and my favorite to date. Enjoy!
