Comments on your storyline:
+
* Sounds like a long story, makes for a long game too?
* Different 'missions' like traveling, resqueing, infiltrating,...
* Inclusion of FMV
* Oddworldisch (sounds like it could actually be a story happening on Mudos)
-
* The role of munch: he's only there to guide because he knows the way? That means he's not neccecary (spelling?) since you can go and try to find the way yourself. Could you give him a misson also , combined with Abe?
* What ennemies would he encounter. (Re-use existing creatures, or creating your own?) I would like to see both.
The area's you describe sound like they smell awefull, can you include that too
