The game is short (five levels), and shouldn’t take long to play through. If you find a level too frustrating or difficult, you can use the "N" key to skip to the next one.
You can find discussion related to the game and a link to an old, more challenging version with a time limit at the TIGSource Forums.
Some kind words:
Awesome effort (Alex Higgins, Zandair Studios).
Wonderful. At first I thought, this is like SimAnt. I changed my mind. I don’t remember ghettos and Gatling guns in SimAnt (Jed Davis, NG Comments).
