# Space Strike
### Game Design and Planning
1. **Game Objectives**: Defeating all enemy fighters.
2. **Game Levels**: Random map with an increasing number of ennemy figthers per level.
3. **Game Assets**: 
4. **Game Mechanics**: 
1. **Player Interaction**: 1st person view. Tap to shoot.
4. **Game Loop and Events**: Objects updates occur in the game loop. Input events are handled in input functions.
5. **Scoring and Progression**: Player's score is updated when killing ennemies. When no more ennemies game switches to next level.
6. **Game Over and Reset**: The game is over when player's lives reaches zero.
