That's great! I'm glad to hear that the game is working out.
Yes, you can play it like connect 4. I usually explain that it's more like tic tac toe, except you need 4 marks in a row and not three.
Another fun rule is to tell them they must build off from any one of the sides or adjacent to another mark already on the board. That makes it a little more of a strategy game.
One thing different from battleship is that this game allows for the same axis points. In battleship, you need to have every square on the board refer to unique points. With this game you can have the same item listed multiple times.
