A flash work of art.
Okay, I have never written a newgrounds review, but if I was going to start, this is the best place.
Your entire mario bros z series can only be described as a work of art. The story is fitting, the action is intense and VERY well executed, and your sprite work is some of the best I have ever seen. I have watched your series four times in the last two days, and each time I have spotted something different that I hadn't seen the time before. The only scores this move lacked in are interactivity (press play, pick a scene, and hit space isn't exactly 'choose your own adventure'. NOT A COMPLAINT!) violence, because there's really no blood, (Again, NOT COMPLAINING!) and humor (wario and waluigi are funny as hell, but it doesn't make up much of the actual movie.).
Overall these movies leave me drooling to see the next in the series (could the chaos emeralds breed a happy ending for sonic, his friends, and all of mobius? Hmmm...).
I hope I don't sound pompous in saying this, but, Alvin-earthworm, the title of flash master fits you too well.
I salute you, and beg that you continue this masterpiece. The web cartoon fans NEED an artist like you running the show.
