I think I fixed the loading problem. Can't really do anything about the saves though. It's now trying to load the saves from chat.kongregate.com instead of assets.kongregate.com
It looks like the Kongregate API changed causing a possible loading problem. It's not clear whether it's a problem with their API or not. Possibly related, my save game is also gone. It looks like Kongregate changed the save location.
@Cosmix360: The reavers aren't invincible. If you look at their ability it shows they have 2 armor which means it negates 2 damage. So the best way to hurt them is with high damage towers like the sentry.
Shirazz, did you complete all 25 levels or just the last level? Perhaps you skipped one of the optional levels?
Also, make sure to disable any flash blocking plugins on kongregate if you're trying to get achievements.
@Mr_Happy_NL: That's funny, I never thought of using that strategy to win a level. Of course on the downside you can't unlock the bonus levels by getting all the data cores using that strategy.
@tonnytay60: If you're having difficulty you can try the walkthrough (click the button before starting the level) or change the game difficulty in the options.
A sequel is likely, but we're going to take a break for a few months before deciding for sure. This game was in development for the last year so I need to recuperate for a bit.
@osanseviero: Can you explain how the walkthrough is wrong? Keep in mind you do need to use the Garbage Collector to clear some of the spaces. If you're still having trouble you can always switch it to the easy difficulty.
@blarghedy: I just uploaded version 1.8.2 which *should* recover the corrupt saves. The bug was caused by saving the game while it was still loading. If the game was saved again after that it would be fixed. However, if you have multiple saves or loaded a game with starting a level it would get corrupted.
Sorry for that loading bug everyone. It got introduced in 1.8. It should be fixed in version 1.8.1 that I just uploaded. Unfortunately, I'm not sure if the corrupted save games are recoverable. :(
annie034: Try leave the medics alone until the end of the level. If you're still having trouble try checking out the walkthrough.
Skyangelc: Where exactly is the walkthrough for level 25 failing?
captingray: I think someone else mentioned that problem. I'll try looking into this later.
jakewf: good question on why it's called Ghost Hacker. The story never really touched on it, yet another thing I forgot. Basically the character no longer has a body and only has their mind, or ghost left. The term is actually taken from the Ghost in the Shell series, although there's been numerous other cyberspace references to it.
The next version will slightly improve the random color cycling. It will skip color sets that have the same colors as the last one generated, even if they're in different locations.
