As long as you keep attacking you can stun entire groups of enemies and you're untouchable. Also everything is incredibly slow and you should be able to move down and sideways at the same time (or at least be unable to move up and sideways at the same time)
A lot of these guns are really fun to use and experiment with different combinations. It's too bad we can't farm money or even see what weapons we should save up for. I would've had loads fun trying out all the guns if we could

You have to get the watch tower but if you use one road spike the tower will start shooting at them, popping bloons that they can't see. One spike is all it takes for the level
