This game is amazing. Its super fun and like pretty much everyone else, I love this game. If you are thinking about getting the game and end up reading through all of this (thx btw) here are some tips.
1) Don't rush through the game as fast as you can. This game is meant to be chill... unless you're doing the rush gamemode then that's a different story.
2) make sure to buy the highwalls and the air net for your corals before you put slimes in them. They can jump really high.
3) If you feed a slime another slimes plort, it becomes a largo that shares the aspects of both the original and other slime. This can be helpful when combining one slime that is easy to feed with one that requires/favours meat.
4) look out for the tar. These guys come from feeding a largo slime (tip 3) a third plort. This guys are hyper aggressive, can multiply by eating other slimes and anything really and love attacking ranchers. Make sure you have a full water tank on you at all times.
5) Find the map for the area as fast as possible. This can be really helpful for exploration.
