Fundamental Tower Defense

This game stresses the limits of a players patience.
Each wave has its own unique ability, and it's up to you to figure out what they are.
You can build a hidden super tower, if you can find out the secret.
Beware of the final boss -- It's game over if you let her get to the end!
The instruction may not be entirely reliable, so be aware of that.
I would demand each of you to make a comment, but at the same time, I don't want to pressure you into doing so since I'm such a nice guy.
Well, that is all for now. Enjoy the game, and try not to chuck your keyboard out the window!

3/4/10 - Added monster descriptions and lowered the difficulty by a tick.
3/4/10 (Second Update) - Seems that you guys were physically abusing your keyboards (or any other hardwares you may hold a grudge against) for the entirely wrong reason. I'm happy to say that the speed is now fixed.
3/13/10 - Lowered the difficulty again and made some unnoticeable changes in the interface. Still working on the lag triggered when the start button is clicked.
3/14/10 - It seems that the upload from yesterday has caused a glitch where stage 15 became impossible to beat. That issue has now been remedied.
