I think the 'maker' of this game has made Shock Defense too. Isn't it strange that there are aliens too as ''creeps' in Shock Defense? Shock Defense is a rip-off of Flash Element TD and this from Desktop Tower Defense.
1/5
I don't see a reason why someone could possibly like this game over Desktop Tower Defense. This game has got hotkeys, you can send waves faster, each game here takes too much time, there are a lot of modes in DTD and you can submit your score..., etc..., etc...
I have been playing this game for 1 year (before i knew of this site), so i can't say it's easy, but i got the hard and impossible badge on my first try. (on this site, i have achieved the same goal on the main site too)
There are tons of people that have completed hard mode and the 100.
The 100 isn't impossible without juggling (that tactic that fools the creeps) though. The game maker hasn't considered this as an exploit, but as a feauture. In all the games where you can maze, you can juggle.
If you don't believe it is that easy, try searching at youtube or something...

First off, great game i like the puzzle genre much.
Second, level 9 is got to be the most annoying level out there for newbies. I have tried almost all the possible combinations and still cannot get past the first labyrinth. I'm going to check the walktrough i think though.
I don't want to know how many effort you guys (that completed the game) put into this game.
