Keep working on it

Its not a fine piece of work, but with time and practice you can move on far.
Get yourself a preloader as the music will cause loading issues and the movie freezes.

Don't know what happened to your first flash...

But I really liked your second flash. I wonder what made your first flash not survive, cause you've got talent in terms of drawing for sure. You certainly know your way around colours and shapes.

Animation wise, it's relatively smooth. Though I must say the whole thing is maybe a bit short... I hope you keep making more flashes in the future, cause I see you got potential.

I like the music.

I like the music, but that's about it. The animation is okay. Maybe add a story line, and make it interactive and you'll have a good side-scroller.
