Maybe instead of flags, it can be some working mudokens, or maybe just Alf
, that Abe has to save, but he has to make sure that none of the other sligs can see him with the help of the shadows or something like that. Also, I don't think that it would be too bad to have the sligs use their incomprehensible voices like in that one cutscene from the original game since there are hardly ever two sligs put together in the same room anyways.
