So, I've worked much more on Mohawk the past week and a half, and I've added some new features and squashed some bugs. I cannot crash Riven anymore. :P (In addition to all the good Indy news... not the new game! Fate of Atlantis on Wii! :P)
I've also added support for the "water effect" of Riven, so it adds a cool touch to the background. The Rebel Tunnel puzzle is also beatable, meaning you can visit the rebel age (aka Tay). ;)
Today, I also worked on the videos again, and I pulled something off! See here for yourself!
As an extra bonus, here's a video of Riven too!
