This was the first videogame that I did. This is a classic Space Invaders videogame without any graphic motor (and without sound), this only use default Java libraries.
You can control the spaceship pushing keyboard arrows right and left, and you attack pushing spacebar.
You can download a executable file of this game in itch.io
IMPORTANT NOTE: I finished this project in May 2013, and I won't do an update of this anymore.
