As Hen-House Harry, the player must collect the twelve eggs positioned in each level within a time limit.
In addition there are piles of seed which may be collected to increase points.
If the player touches a hen or falls through a gap in the bottom of the level, he loses a life.
Each level is made of solid platforms, ladders and occasionally lift platforms that constantly move upwards but upon leaving the top of the screen will reappear at the bottom.
Playing games on my ZX Spectrum meant that I had to hijack the family TV in the living room and set up my ZX Spectrum and load games by cassette.
Later, I managed to get a portable black and white TV in my bedroom which wasnt quite as good as playing on the family TV but had the benefit of allowing me to play anytime.
