New game

I have an idea for a new game. I think a game where there is something coming at you and you have to repel it to hit the thing that is shooting it with a shield or something. After you hit the master thing so many times it will fall over and you will go to the next level. I am kind of basing this off of a mini-game that I used to play on a computer came by fisher-Price called Great Adventures castle. I believe the mini-game in it was called Tower of Terror, or something like that.
