I relay like this game, the control is some what hard to work with, maybe mapping your controls to the arrow keys would make it simpler to work with, i relay like the natural order way the game works where eating and mating are your objectives, I feel like mating maybe cost more then it should but it is probably ok. something you might think about for the future is maybe getting to change your birds gender, maybe if you are female your score goes up faster but if you are male your engergy drops slower, what do you think?
