Scratch - Abattoir Game (keep the horses out)

I've been trying my hand at Scratch, I wanted to see if I could transition myself as a traditional programmer to it.  Learning how Scratch was structured was probably the biggest challenge, but once I put the structure in my own language (I now call sprites objects in my head), I got on pretty quickly.

I decided to write a simple game, I fancied something which was topical and, I realise now, being slightly sick, I came up with "Abattoir", the concept of the game is "You get points for getting cows in the mincer and loose a life for every horse that 'accidentally' gets in", if this doesn't celebrate the horse meat scandal I don't know what does.

Play Abattoir here

The controls are pretty simple, click the green flag to start, the red circle to stop and press [space] to open and close the mincer.  Leave it open for the cows which fall off the conveyor and close it for the horses.
