b-l-a-m. thats what is said by your friend sambam
look, i have to level with you here, man. it was cool to see what are ancestors used to play, but..it sucked the very space balls that were hit around in the game. i might have still been interested if i lived in the stone ages, or if the cold war was going on, but i dont, and its not, so. sorry bub.
So dull
If you added space mechanics, such as black holes, alien bumpers, etc., it would have been much more entertaining. Secondly, it needs music (I might suggest anything by the Babylon Zoo, known for their track, "Spaceman") for it to keep people occupied. The AI was far too simple even on hard. There needs to be a bigger playing space because, since it is this small, you can't really lose unless you are a terrible Pong player. Also, tone the background down, add detail (i.e. planets, stars), or change to color of the ball and paddles to something that isn't the same color as the background. Powerups might also be nice.
Easy, kind of boring.
Like the others have said, it needs sound/music. and it is stupidly easy. Amp up the difficulty, add sounds/music, and perhaps try to just make it more exciting.
impossible
impossible to lose, that is
easy
I beat hard without moving the paddle at all.
