Commodore v0.6 Update

With more time on my hands, I've been adding in a whole bunch of key features. I've been starting to work on ideas for turret defense gameplay. And, I need a name... If anyone has any idea please share them. You will get credited.

Anyways, some new features:

In game zooming! Now simply press the plus or minus keys to zoom in or out.
Added a tiling system. It still needs work, but it reads data from an array and displays tiles based on array values. Picks tiles out of sets of similar tiles to make maps that look less repetitious.
Nifty scrolling tab menu thing. It's in the bottom right, you'll use it to select units to place.

One thing I got to say, thank god for bitmap caching, It makes (almost) all of this possible.

And of course, a pictures worth a thousand words, current pic:
