I worked on this game for quite some time. Probably a good 20-30 days of work on it. This is my first ever large scale game and has a functioning high score system by rankz.armorbot. (went down long time ago)
I didn't perfect everything yet but I am working on it so criticism is welcome. I am more worried right now about coding problems and glitches than making the jumping and collision detection perfect.
I also used a template from flashvillage.com to create a little movie about the making of the flash game and what goes into creating something like this.
