Big physics stability improvement. There's now a noticable stability improvement to the puzzles where there used to be a bit to a lot of jittering as the puzzles settled, now there is little to none.
Another level of optimization removing a few thousand extra polys, so should run even better on lower end supported machines.
And Korean language support! HTC is from South Korea and I thought why not add Korean? My friends wife is Korean and was gracious enough to help me with the translation. Thank you Caroline!
