Lots of progress over the last week! The speed boosts are in game along with the fixes to the Wolf; increasing the size of the Critters and replacing the plane with a square seems to have solved the previous issues. I initially had trouble getting the speed change to apply to both the Rescuer and the Critter, but eventually figured out that I needed to use .Get Component <> to equalize the two speed variables. The Corral is now implemented and works by displaying a counter of how many Critters are brought to it!

Next on the list:
-Final level design and polished features
-Rotating cameras?
-Square shaped corral
-Disappearing speed boosts
