I have to agree with luke-brown about the speed, although I did get somewhat used to it after playing trough the game once. The second map was the hardest one for me, all the waiting required made me impatient, which led me to try to rush it, which lead to restarts and more impatiance...
Ran well under Arch Linux. Only bug I encountered was that sometimes the cops would get stuck trying to turn around, which on at least one occasion led to me having to restart the level just at the end of it.
