This is the Linux version of Galaxy Blazer, a simple arcard shooter set in a 3D perspective, it is very difficult XD I'll be looking at posting an easier version.
Avoid and destroy various obstacles and enemies.
Collect power-ups that heal you, give you a temporary shield or improve your ship's weaponry.
Play through nine levels in the main game, or just jump into the Arcade Mode
for an endless run, with two difficulties.
There is no installation just extract the game files, then you'll need something that lets you play executable files.
