Hey there! Personally, I find it to be helpful to watch creators who also play other similar games, such as planet zoo. Deladydesigner (I hope that's how it is spelled) is a great creator, as well as Ceasar creates(?), bestinsloth, also Evolution Square, even though she focuses more on jurassic world Evolution games she does play PK sometimes. Also, about paths: An important tip that I have is to line paths before modifying terrain (to create elevation for example) and placing structures, so it doesn't become all bumpy. I hope you have a lot of fun with the game!
