So, I went onto this game --being a Tower Defense fan from the genre's origin on Warcraft III Battlenet-- expecting a failed attempt to mimic greatness with a flash game. And I was wrong. It is indeed challenging and complex, and more importantly the mechanics are very difficult to overwhelm/break.
http://armorgames.com/play/4962/bubble-tanks-tower-defenseAfter a few levels, I decided to try the one-way infinite challenge. I made it to level 1000. I could have gone on much longer if I hadn't sent the last 100 levels at myself simultaneously, and if I hadn't lost all but 2 lives in the first few levels, or if I hadn't destroyed my anti-air tower and rebuilt it wrongly, or of I'd simply juggled the creeps. That's a lot of mistakes. But hey, it was a first try and it's a sure bet I don't want to try it again.
My challenge to you, fellow Bay12ers, is to beat me. You'll need to play the short tutorial to unlock the infinite one-way challenge. I think the score counter broke during my game, so you can use the remaining cash tally as your marker. I don't think that one looped. That would just be insane.
So, who will be the best!? Certainly I won't sit at the top long.

Edit: Ah, I forgot to mention: this could take around half an hour to an hour, depending on your success. You have the option of sending the waves of enemies as quickly as you want, which is what will keep you sane and prevent it from taking forever.
