I'd suggest you not worry about all the aspects of game development but focus on what you enjoy and can do well. There are programs like Unity that can fill in the gaps for you or groups of people you can get together to have these various skills.

@Iscalio Aw thanks, maybe once I get better at the mockups (and programming, I only know so much) :)

y u no make real game? 

@jalonso, @Limes: Aw, thanks guys. :)

Good job, looks readable and the colors are pretty nice. Grass could use a little more spit but solid overall.

You made a great effort and worked hard.
Hope you take some new knowledge to your next pixel.
