Compared to the original, which I very much liked, its really nice to see a refurbished version.
The new graphics improve the game a huge deal, the only negative thing to say is, the bullets were easier to spot and avoid due to their sharp edge in the original version.
What I really like more in the first version, was the music and sound effects.
That gritty drum and bass got me going and the old retro sound effects fitted nicely.
