Hi, you are right - it looks like I played the old version again. I have now played the new version (with a different looking menu) and it does play better. Maybe due to having less chickens on screen at any one time?
I did have a wander round the farm and it is great looking and well thought out. I liked how the chickens would follow you (specially the big ones).
There were a few places where I found an 'invisible wall' and the bullets would bounce back rather than towards the chickens.
Is there only one level? I could only select the first one.
And I didn't seem to take any damage when hit by the eggs?
