I've changed the main menu screen to not show the option for "Continue Game" if there is no saved game, instead of showing an error message.
First bit of gameplay is done. The game screen now shows the Tribbles added to the board. A row of Tribbles "spawns" at the bottom and as the row completes, they move up onto the board. There is a spawn animation for each of the tribbles on the spawn row, and randomly the tribbles on the board will do a blink animation.
If you click 2 or more tribbles, (match), they fly off the screen in random direction. Then the board should then collapse down, but this is not done yet. Oh, and I have a few different sound effect for when they fly off, it plays a random one.
