I can't unfortunately because of sitelocks... part of what Flashpoint does is in Man In The Middles the Flash Player so it thinks it's on a certain website, which allows the games to be played offline. You can play these games on Kongregate and Newgrounds if you have a flash enabled browser though. Sorry about that :/
In terms of tower defense, here's some recommendations:
Ghost Hacker (the original one, which is better than the 2nd one)
Defender's Quest (trial version, complete game on steam)
Kingdom Rush (also available on your phone)
Cursed Treasure
Demons v Fairyland (feels very much like Kimgdom Rush)
