Super Simple Script Snippets – Part 2

This is part two of my previous post of fun code trickery. Click here.
I’m thrilled with how development is going. It will definitely be a fun mobile game.

Like I said, you can find more in the Open Source Directory. Click here.

So… I should hit “Publish” now before I get distracted too much with my blog. :)
