Sadly I didn't have enough time to add all of the features I wanted to.
I was planning to have the 'attackers' change over time, i.e. become more sophisticated, change in appearance, perhaps use some tactics. Sadly I didn't have enough time because this was my first time using FlashPunk (You'll see that the video is about 50% tutorial). I also planned to make 'upgradeable' defences/weapons (Over time you'll be able to 'research' better tech.
There is a missing part in the video where I remembered that I couldn't borrow the Windows XP background.
Hopefully next time I'll be more comfortable with flash!
Wish you had more time, it seems you didn't have enough to add stuff that tied it in with the theme. Music is good, better then anything that I could make.
For such a simple game, it was surprisingly fun. I really liked the manual activation traps, and the death animation of your enemies. A full fledged tower defense where you have few enemies and towers, but you have to click the towers to activate them, would be quite interesting.
The music was not bad at all.
The game (even what you planned) kinda passed far away from the theme though. Evolution != upgrades.
That's too bad the game is not finished.
