On friday afternoon, I played 5 hours straight of one flash tetris game on the Wii, and got the second highest score
The reason I screwed up is that there was a sudden quick down pour of rain and after it ended it got humid and hot. I ended up sweating and I have an issue where my own sweat makes me itch, and I was way too close to the top of the screen to want to pause. So yeah, I died
Check out my score in "Global High Scores" on here:
