Some more gameplay action:
I added in entity/entity collision, shadows, a new enemy type, the frost cannon, and reworked some of the particles. It still isn't much of a game, but you might find it entertaining for 3 minutes.
Controls: WASD/Arrows to move and mouse to aim. Left mouse button to fire the plasma cannon and right mouse button to fire the frost cannon.
There is no real specific aim to the game yet -- it is perpetual. The eyeballs will continually spawn at a successively faster rate and eventually the 'mangler' will show up. You can kill the mangler, but he will continue to respawn as well. The only real metric in the game is the 'souls' counter, which is reset if you die. But even that is a fairly shallow metric.
For now, hopefully it is just enjoyable to splatter things =)

What's next? Well, this was just a small diversion from Gearo, which I am working on right now. I may come back to it from time to time to make it a real game, but I am open to suggestions on how to make it a real game, instead of a spawn-kill fest...
