Shear genius.
__The Good__
The graphics were phenominal! I loved how you made the classic characters from Mario into something so dark and evil. I also loved the surroundings. Great style to this, you made the well known Mario into something a lot different! Also that song was just perfect for this flash. The sound effects were good as well. Great violence! I loved how you made Mario wih a gun, it was great. The blood spray was awesome as well. The ending was just the iceing on the cake. It really made me laugh and was unexpected.
__The Bad__
I wish you used some voice acting, it would have been nice to hear what you could have done with that. Also it would have looked awesome if you had a scene where Mario used his fire ball technique to burn one of his enemies. That would have looked so cool!
__Over All__
Over all this is an awesome Mario parody. Everything was perfect. From the graphics to the music. It also had some humor with all of the violence going on! Next time I just hope you use some voice acting. Great job making this flash, keep up the good work! I look forward to seeing some more awesome flashes from you!
