Well, it may be actually used for enctrypting/decrypting e-mails between friends that are afraid of someone else spying their e-mail sent box and inbox! ;-)
Even most of the easy levels are too difficult... talx01, be aware that most of the people want to pass a level if not from the very first attempt, then within 2-5 attempts; more than that is just TORTURE and makes people quit the game!
The man doesn't jumps high enough before enhancing the jump. It is also bad idea that after a death, it reverts to the beginning of the level, instead of some closer position prior to death. So, only ** from me.
PeaTear_GriPhan, dont't ask too much from a begiiner's game. It's working fine with no bugs, and that's the most important thing. Yes, there is only one tower type, but no one enemy: haven't you noticed that there are fast and boss enemies, also?
Mr 209617332, I've also passed level 6 twice, with only 1 life lost (only when you kill 2 of the 3 boss enemies in level 6, you have enough $ to fill the whole map with towers, so I'm sure you've passed it, also). After that there is no level 7, but rather a congratulations message "You have beaten the game!"
Yes, I got scared :X mostly by the annoying screams; especially I didn't expect a scream after the successful completion.
The so-called "right click teleportation" is a BUG in this game (just like in many other beginner's maze games): right click near the starting position, then move your mouse few pixels to the red goal, left click there and slide to the goal.
I would also like to encourage you to continue developing Flash games. Another thing I want to suggest, is that there are plenty of players (especially those "aged") that have no such fast reflexes, i.e. that usually get the ball destroyed within 10 seconds of playing; so also try to develop games for such "slow" players, too.
About me: I'm a professional mathematician, the best graduate of my Faculty in 2003. When I was asked by my menthor "What's the purpose of mathematics?", I had answered "To classify (objects)".
The modern mathematics has gone farly beyond the simple arithmetics (the four basic operations, you are focusing in this game). So, to claim that the addition of integers is mathematics sounds ridiculously as to watch the night sky with a naked eye and call that astronomy, or to hit the desk and call that rhytmic music.
