Build 0.8

This week, I added a third world and am mostly done the content which the game has to offer. I have also worked on the visuals of the game, as well as added some music and sound effects. I feel that I can finish the game in one more day.

Something I've never addressed is the name of the game; Power Operator doesn't really fit anymore since the game is about animals, so I feel that Operation: Animal would be a nice name.

Some other quality-of-life features I've added are the replacing of the numbers in the goal bubble view to silhouettes of chickens, as well as a level end screen / menu.
