0.6.0
This release introduces automatic play where the computer automatically begins playing the game after some idle time. To see the automatic play in action, go to https://susam.net/invaders.html, press enter twice, and wait for 5 seconds.
The automatic play algorithm is quite rudimentary. It sometimes makes mistakes. However, it has been found to reach level 12 a few times. That's better than any human is known to play this game yet. The automatic play algorithm may be further improved in future releases. However, the current automatic play that comes with this release is quite fun to watch too!
