pretty good concept, the last level made me give up and honostly really showed the issues with the smelling mechanic, feels like the players scent is way too strong bc once he gets a single sniff off of you he never loses scent, either make the rate at wich he sniffs a bit slower or make the players scent weaker but the rate faster, maybe also make it so that coal makes the player smellier when holding it, otherwise no real notes, pretty good
also one idea for an update (if the game gets updated again) a mechanic where cobb is blind but can feel the envireonment, this would make him faster because as time goes on he gets a better sense of the map, making him know the layout better and better also making it so he'll have a better idea of where to go to maybe cut you off or catch up, if paired with the cobb can hear modifier this would also make it so he can hear a bit better
