Post Jam Update 1.1

Updated to v1.1, fixing a couple of bugs and tweaking the stats post jam.

- Fixed the boundary logic, so Duck Norris can't move out of bounds

- Adjusted the defenses of most of the mobs. Turns out I'd set the starting defense incorrectly for a bunch of them.

Also upgraded the project to Unity 2020.2.0.a9. Because we like to live dangerously.
