(Casio PV) UFO

UFO was the first game I wrote for the Casio Pocket Viewer,  back in 2001. This is version 2.0, that included different types of ships, better city graphics, etc. It was very well received by the PV community, back then.

Alien invaders are descending upon the city. Zap the UFOs by touching them with the stylus. The city achieves damage as invaders reach it. The game ends when the city is completely destroyed. The number of invaders increases each two levels. Their speed increases each three levels. During the game, you can quit by touching any hard icon in the right half of the panel.
