How to Design a Game That Works

Every single object in the game had a boiling point and a melting point. When something hits its boiling point, doesn't actually boil, it's just like the temperature is high enough in the area. It's very hard for a lion to hit a boiling point. But if you click, put lava and fire all around it and wait, then the temperature will raise. Some of these were design decisions, but a lot of them were also technical decisions.
