The graphics weren't great, but that isn't always necessary for a game like this.
It would help if there were instructions for how to play each game. Perhaps instead of instructions, there is a larger demo of the goal of the game, I can't quite make it out from the menu.
When replaying game1 I had to click on the chicken before the arrow keys were responsive again. Also on game1 the eggs dropping were a little TOO random. sometimes the egg would drop too far away from the previous egg to collect.
