Harry Potter Game in JAVA

We have a basic Harry Potter game project in Java. We should have Harry Potter, Voldemort and Bellatrix Lestrange in this game. Game should be like this, Harry tries to hit Voldemort. Harry has 20 spell power and Voldemort has 100 health. So Harry should hit to Voldemort 5 times to win. If spell goes to Bellatrix, there is no harm for Voldemort and there is also one blocked spell. Game should contain timer that shows how long the game takes. Also, there should be Harry Potter theme song, a start display. Harry can move only in x- axis and he only spell to y- axis. Voldemort and Bellatrix are not going to spell back, they should just move across x- axis independent from themselves. We want to write "expecto patronum" in display that looks after the game, timer, the number of spells that blocked, how many spells spent. As I said, we need a basic game, not too much detailed one. People who are interested in making the game can contact for details.
