I don't see this mentioned anywhere, but I just downloaded the fallen levels, and when the introductions for the new levels start, the voice-over is way too fast and barely intelligible. Is this a known issue? Is there a way to fix this?
On non-Mac versions earlier than 1.4 the narrations will play at double-speed and sound like chipmunks on helium. Basically because back the narrations are mono, whereas the old PC/Linux Myth expects stereo and plays it as such.
