I just beat the whole game, so I have to share:
It’s called Ghost Hacker, and it’s a bit different than your average TD. Instead of upgrading towers, each towers has certain points where you can attach functions. There’s some sort of story about A.I.'s and evil cabals of whatever, but I stopped paying attention halfway through.
Normally I’m pretty mediocre at TD games, at least compared to the people who post on TD messege boards. “Oh, I think the last few levels of Extremely Hard Insanity Mode were too easy, there were only fifty creeps per tower at most.” It give me an inferiority complex when I’m struggling through Easy Kid Mode. So this time I said to myself, “You say it’s easy? I’m gonna beat Ghost Hacker perfectly on every level, or explode my brain trying.” Well, it turns out that if you get perfect scores on all the levels you get three bonus levels that- well, I wouldn’t want to spoil the surprise. Suffice it to say that it was a surprise.
My spell check isn’t working, so I’m going to have to cut my ramlbing short (or at least use smaller words). So, uh, it’s a fun game. Check it out.
