Hungry the Monkey
Hungry the Monkey was the very first iOS game, and the first game as a matter of fact, I published. As such, it certainly means very much to me.
It requires the player to feed Hungry, who is a monkey, by tapping on any and all the food whilst avoiding feeding him poison.
The game is bundled with a variety of gameplay modes and two 'food selection styles' allowing for 8 different gameplay experiences.
