uhhh...
yeah this wasn't very good. despite the animation being exceptionally choppy, the plot line was lame and it seems like you didn't even write it, you just made it up as you went along. even something as simple as making luigi walk with 2 frames of sprites looked choppy. you need to learn more about fps and motion tweens, etc etc. also, don't rush! i know you were probably anxious to put this up on newgrounds but you really gotta just be patient. the longer you spend on it the better it will be. don't let me get you down though, just keep making movies, come up with new ideas and no doubt one day you will spit out a really good sprite movie. sprites have endless potential, keep working on your skills. peace.
