I liked it and played it on Kongregate. I found an almost unbeatable family (I DON'T recommend you use this before beating the game, since shooters are weak without lots of upgrades). In my family I had 3 female shooters, each with 5 upgrades: quadruple damage on the first shot, 50% chance of 1 second stun on each shot (this used 2 upgrades), +15% fire rate, and 10% chance of shooting a second bullet. For Items I used a coffee cup (+5% fire rate), a diamond ring (females do +5 damage), and an old pistol (shooters do +5 damage). With all these upgrades I went on a winning streak of 103. Usually I am able to kill at least 1, and maybe 2 or 3 of the enemies before they get close enough to hurt me, and the enemies constantly get stunned so they can't do anything.
I finally lost a game, breaking my winning streak, against 2 bruisers and a dog. They just had too much hit points and healing. But then I replayed that match several times and was able to win each time - the key was, first, to focus fire on one of the bruisers, then take out the dog, then take out the other bruiser.
