Revision is very bad. There are changes made to levels that don't make sense and completely break the flow, or worse, the tension of the game. The "enhanced" graphics aren't good enough to tolerate that.
I don't really understand how one has the nerve to ‘fix’ levels in a classic game. But at least, I vaguely remember reading that it might be possible to disable gameplay changes in ‘Revision’—haven't tried it myself yet, but I'm planning on only enabling graphics enhancements.
Also, the Chinese hanzi in Hong Kong were gibberish.
