The game is set to fire the puck at you very fast; there's no way to vary the speed. It's nearly impossible to beat, I was trounced every single time.
The "opponent" virtually never misses returning your shot.
In this game, the cards are stacked against you regardless of how hard you try.
The more I played, the more demoralized I got. I eventually thought, "what's the point of continuing, this just isn't fun", and trashed the game.
The developers need to incorporate several difficulty levels, perhaps programming the game to "sense" the player's level of expertise and accommodate itself to it, while still keeping the game a challenge.
As it stands now, one leaves the game with the feeling of having been relentlessly kicked in the stomach.... which might appeal to a masochist, I guess.
