... this is a really, really good game! I mean, c'mon, who wouldn't want a non-violent Metal Slug game? The graphics, whilst obviously based on the Metal Slug sprites are creative and very well drawn, the animation is superb and the whole game oozes style. The sound effects however, were "only" adequate (but really, it couldn't be much better in any case) and the music, although good, extremely appropriate and well selected, was a bit repetitive... almost inevitable in a game like this.
The gameplay was, however, flawless (albeit a bit slow, but that may have just been my computer), the level design was very creative (although the narrow corridors are a bit of a cheap death, no way to jump out of the way) with the same going for the enemies and weapons design. Or better yet, they were Very creative! This is really, really good stuff, extremely well made and it the effort really shows. Congrats and kudos for a truly excellent game!
