Pretty good game! I can see that the AI needs some work because it was so slow to build units that they only was able build 6 Units before i destroyed theit base.
Sounds like you are on a Mac. Are you? If so, you'll need to quit the browser or maybe even restart your computer. Sorry about that, it's a Unity3D problem and we're trying to fix it ASAP.
Hehe, the AI is pretty bad, but it's also brutal on a lot of new players. We really need to make it possible to change the difficulty :)
