If you're one of the many people that played through and enjoyed the first installment of The Ball for UT3, you'll be excited to see the first footage of the second, The Ball: Oztoc. A forum update reveals a little bit more about the overall progress and what you're seeing in the video.
The puzzles shown are simple. I didn't want to show the complex ones as that would spoil the challenge of solving those. We now have between an hour and a half and two hour of singleplay gameplay dependent on your playstyle.
Couple of small issues left, and also the monkeys are missing. Working on those. Release is planned for this weekend.
