Played this game when I was young and have fun... but couldn't beat it at one point in the game... couldn't figure up where to go next.

Remembered playing this as a kid and being so happy each time I solved a puzzle and progressed with the game, managed to beat the whole game with my sister.

I played this when I was a teenager, somehow I cannot beat the game no matter how hard I tried. The population grew to a certain level and then began to go down.
