A lot of people take this game for an Arkanoid-based game. They couldn't be more wrong. Astrobounce is a design that stands on its own and wasn't based on any other game.
NOTE: Originally this game was called Astroball, but back then I didn't know that there was a Z80 game with the same name. In order to avoid copyright claims, or angry Z80 fans expecting a remake of that game (which this game really isn't as I never owned a Z80 and thus never played any game for that system) the project was renamed to "Astrobounce". It is still possible though that some files were not properly updated and that the old name remains. Let me know whenever you see that so I can remove or update it.
