for the competition we will use all object types that occur in the first 21 poached eggs levels.
That is objects made of wood, glass, and stone in the typical shapes. Of course also the typical static objects such as slingshot, platforms and ground/mountains.
We will use the red, yellow and blue birds, and green pigs with and without helmets.
If enough participants request it, we could possibly also use white and black birds and TNT boxes. But even then, we would only use them in a very small percentage of levels. So if you want those, please let us know.
All this will be specified in the detailed competition rules which will be released in early May.
