Well............
I am a generous rater, but this is one of those rare ones. I have to agree with mike1225 that you should make it so you don't die in two seconds. The problem is more in the fact that you can't make the first jump. It's also a problem that the Jump key is Shift instead of the usual Up arrow, W key, or Spacebar. Modify it to one of those and make the jump smaller. The enemies seemed numberous so scale them down a bit. If this is your first game then its ok. If not, try harder. You still have put up more games then me so I can't say this is too bad.
