Not so much a game, but a quick animation about how to fill in your free time! PS follow me of you like it!
If you need to create a conversation between two or more sprites, get one to say something, then broadcast it. You cannot see or hear a broadcast, but it is a way for two sprites to communicate and create cues for each other to complete and action. Then you add- for the sprite you need to talk or whatever- a "when I receive" block of code, then the action.
