Another game I am working on for the 4K.http://marber8.freehostia.com/defend.jnlp
Pretty simple so far. Use the mouse to rotate your shield around the planet to protect it from incoming asteroids. Each hit that the shield takes reduces its size a little bit. If an asteroid makes it to the planet the shield reduces by a larger amount. Your shield will never go below a certain minimum size. It also regenerates continually, so it will eventually get back up to size if it has a long enough rest. I will also go back to maximum size between levels.
I am thinking of adding a laser type canon and a bonus level that occurs every 5 levels to add a bit of variety. I have about 1500 bytes left, so I should be able to fit that in.
All comments are welcome.
