This was a pretty slow paced game. All the characters move around pretty slowly except for maybe when uber kid charges you, and even that is pretty slow.
Friendly fire for the enemies makes this game incredibly easy, just let the Dan Paladins stay alive and they take care of a lot of the enemies for you (including each other). The most effective strategy is to sit in the middle crouching and only firing at the uber kids, the spiders, and the thingy majigs. Only the spread shot Dans will hit you and the other ones will take out the other enemies.
And finally, you can take like a billion hits of damage. I don't even have a clue how many hitpoints Pico has because it was impossible for me to die.
To make this game better, make it faster paced. Add more ways to attack than just shooting in one direction of the other (maybe some melee combos), add more enemies, and make the controls a little smoother.
This is a good concept, but unfortunately has a lot of flaws and is overly repetitive.
