Progressing & Keeping It Simple

So far it seems to be going well.  The game is far from finished, but all the elements are falling into place.  This time I made the effort to stick to the principle of keeping things simple.
For example, I had an idea of letting the stage being "circular."  That is, if you go off to the end, you are at the beginning again.  However, after some thoughts, I realize that the implementation would include more complicated coordinates calculation, graphic display issues and host of others, without improving much in terms of the fundamental gameplay, so I just drop it.
I guess it is true that for small project, stayed focused on the fundamental elements is really important.
