Day 5: Opossums

On day 5 I implemented the final entity, the Opossum

This little guy will walk around the level, and knock you away if you touch it

I also began implementing high-score uploading, with no visible results yet.

I also finally changed up the "Chicken" texture to actually look like a chicken (thanks to https://awkward-berd.itch.io/fully-animated-pixel-chicken)
