dreaming

Hi everyone, first post :D
well i've always wanted to make games, so i've decided to start my own project.
im totally newbie in the art of making games but i've been reading a lot and i've been thinking how it could be, anyway this game is about a kid, who wakes up in his own dream and he is concient that he is dreaming. In this dream, he is in another world, a world with less gravity than ours, so he started thinking a way to wake up. he remembered a ravine he saw somewhere in this weird world and he thinks that if he jumps the scare will wake him up, but as i said, this world has less gravity than ours, so he fall slowly and didnt wake up, so basically he needs to fall faster, to do that he has to look for items in this particular world, and make something that can allow him to fall faster..
thats pretty much how imagine my first game, something simple, to learn the basics.
Any help would be very appreciated, any comments, thoughs, whatever.
Forgive me about my english, im not good at it, but i think its understandable.
:D!
I'll start working on some pixel style character, possible scenarios and all that.
Wish me luck :D
