Wow.
When i saw "first submission" in the description, I felt a bit worried. Amazingly, once I played it for about a minute or so, I liked the feel of the game, and the character abilities were balanced, the items were original, and the challenges were fun.
Try adding more characters to start out with, its always discouraging to know you have to unlock so many characters in the beginning.
The waterfall backround should be tweened so that it looks like its moving, and maybe in the snow level you could make the backround look as if it was snowing.
The lava in the lava zone just fell, and not poured, so it looked as if the rectangle had fallen from the sky.
The characters should talk more when hit or attacking.
Other than those things, this is the least glitchy SSB remake I've ever played.
