The third and final alpha build is now out for download, subsequent releases will be beta builds and eventually the final release, however the first beta build won't be released for some time so do expect a somewhat lengthy hiatus. The current version is, as always, downloadable at our website (see the link in the original post). It features a new unit, the security nodes which are "turret" units that fire packets of corrupt code (orange projectiles) at the player which will weaken the integrity of the player's code (this is displayed by the blue arcs around the hacker node). The security nodes also can be destroyed by this corrupt code if hit by the code anywhere other than their barrel or shield.
All of the known errors and bugs from the last build have been resolved except for one, occasionally the defender nodes get stuck outside of the level, the reason for this bug hasn't been found yet. If it happens, then just restart the level (or just effortlessly fly through it). So... yeah, that's all for now. Check it out and stay tuned for more!
PS: Future updates about the game's development will be posted here and on our site.
