Slingshot

Description
Slingshot is a 1-player arcade game for the ZX Spectrum.
The player tries to detect and destroy enemy alien planets. Gameplay is divided into two sections: in space and landing on alien planets. The player travels to different space sectors by choosing an area on the map to explore
When entering a sector, the game is played from a 1st-person perspective, and fires on incoming alien spaceships and asteroids by moving their crosshair on the screen. After all alien spaceships are destroyed in a region, the player may encounter a planet. On a planet, the game switches to a side-scrolling view where the player must avoid or shoot incoming blocks which drain fuel. If the player reaches the end of the area, they destroy the alien planet for bonus fuel.
The player has limited shields, as displayed by status bars to the left and right of the screen. It's game over when shield energy reaches zero.
