2x0ng is moving along---I've just released Windows and Linux downloads of 2x0ng version 0.6.

So, what's new in this release? There are several new enemies, some bugfixes, and the design of the levels has been tightened up so that there's less free space than before. This, in combination with many parameter tweaks, has made the game a bit more challenging. I hope you enjoy!
