A UFO from planet UMMO, was seen flying over San Jose de Valderas, Madrid, Spain.
Press said that... bla, bla, bla...
Look. This is a shoot'em up game, you know perfectly how it works, then...
Shoot the aliens or die!
This game was developed using MESCC (Mike's Enhanced Small C Compiler - my version of Small C) and some libraries of SAMARUC, my GUI for the Amstrad PCW.
It was reviewed on the Homebrew heroes section of retro GAMER, # 134.
Inside the game is also TWO (The World Of), a game engine inspired in Greenfoot, also written in MESCC.
