Did you want feedback or are you just letting people know?
I guess I'll just post a few comments since nobody else has. I'm working on a game of very similar nature so feel free to ignore my comments completely/put them down to sour grapes.
I must be honest and tell you that I didn't bother playing for more than a couple of minutes. After a few minutes of walk... kick...walk...kick...walk...kick...yawn...walk...k ick... I got really fed up very quickly, to the point that I jumped off a ledge sans-egg to see what happened. Then I couldn't work out how to get back up. I couldn't find a map so I was never really sure where the exit was. I did find an igloo, though.
I'm not sure if the damage meter is broken? I kicked the egg of a good few platforms and it still showed 0% damage. It it, like, hard boiled or what??!
Game doesn't look too bad, but the graphics are slightly amateurish.The sprites/platforms/background graphics don't gel together very well. I think that's maybe down to the black outlines around the sprites.
But my biggest gripe with this game was that it forces me to visit your website when I exit the game, AND when I uninstalled the demo. I really like to be given the option of visiting websites. I also had a quite major problem with the front-end. You should have really incorporated some kind of mouse-over effect, since it wasn't immediately apparent (to me) which bits I could click on and which I could not.
On a more positive note, it does work in Vista.
