A lot of games do scent only by highlighting stuff.
I wanted to make a more realistic scenario where the scent is in the air and the player needs to find the item by themselves.
As the player progresses the player will be able to scent more accurately and not so much deviations when finding items.
This is who the progress will work.
Beginning the scent will wade too far away and fade too often and quickly.
Player animal will be able to remember fewer scents.
Expert the scent will not wade and will be much more clearer towards the end goal.
Player animal will be able to remember much more scents.
