This dis-continued? This seems like it would've been awesome. On an idea note, I think the characters move too fast, slow it down a little. I didn't die when I lost all my HP either. Would've loved to had that boss fight too.
My top tip would be to keep going at it and just try anything you think might be cool. For example say you want to do a platformer, think logically about how you would go about it, what parts are needed, how the code needs to interact internally and how you could do it.
Then just look up anything you don't know, follow some tutorials and keep doing new things.
If you want links to some good tuts i can gladly give you a few.
^_" thanks for the tips mate, shure i would love some tuts, im doing a game for college at the moment, just wont to make it look as good as i can you know i'll link you the final product if you wont to be a "Juge" as it were
