Catch'em All!

This Martian doppelgänger family does sudden shapeshifting, and changing color as you touch them. Rule is simple: same colored members as the touched one choose another form and color. If you chase them to uniformity, till all is evenly colored, they disappear, and you win this turn. There are red and blue girls, pink and yellow moms, violet, orange and azure guys, and a lot more... So catch'em all! You can get back to the main menu: just make a quick swipe, and touch the UFO appearing at the top-left corner.
