Fun & simple game play, that offers a challenge.
The left & right arrow keys, being the only ones necessary to play, make for a simple to control game. But, that is not to suggest, it is going to be easy.
It may seem at the start, that's it's going simple to fly right through the game. But, you find out rather quickly, that with each new level, it grows increasingly difficult. It has the potential to be a highly addictive game, like Tetris, for example. But, sometimes the target falls out of view (which could be part of the intended challenge), the music (at first kind of cool, if not too short) becomes almost unbearable in its repetition & there's no way to pause the game, making it even more difficult to make any real advancement through the levels.
All in all, I think it's a decent little game, with alot of potential. But, for the aforementioned reasons, I find it lacks the ability to be played for prolonged periods of time, which is sometimes what a gamer is looking for in a game.
P.S. There are some odd, smudge-like blurs of color (mainly red), in fixed positions, within the visual frame of the game. At first, I thought something was wrong with my monitor. But, after exiting the game, then re-loading it, it proved to be in the game itself. This may add a further distraction for some.
