The Bullet Hell game is simple yet frantic to play. The game starts with Bob on the screen with a single bullet bouncing around the walls (edges of the screen).
The aim of the game is to survive as long as possible and the game will have a timer so the player knows how well they are doing.
If Bob is about to get hit the player can tap anywhere on the screen and Bob will instantly teleport to that location. However, each time Bob teleports, another bullet is spawned making the likelihood of collision and Bob needing to teleport again (and yet another bullet spawning), greater.
Clearly, this is a game which can only end badly for Bob. The game will also record the player's best performance (longest time) for the duration of the play session.
Note
When we put the finishing touches on the fifth project in Chapter 21 we will see how to persist the high score even beyond the player switching his device off.
Bob will have a 10-bullet shield which will count down with each hit...
