I see potential
Well hmm, I know it's your first flash, but I recommend that you practice some of the basics and then finally when you've gotten a bit more advanced you should resume posting games.
It has the potential to be a fun and quirky idea; it seems to remind me of a Genesis era game or two. The thing is, as Argosas said, reducing the falling speed would be better, aslo there are some areas that you simply fall through even though they're supposed to be solid platforms. I'd recommend animating the Jellybean's face and obstacles. Here's an idea; you could even add some form of jump or bounce meter for some vertical platforming areas.
Keep at it and don't leave this idea behind; keep practicing!
All the best to you
