Hey, this game isn't stolen, because I'm author of this game. This flash port is legally licensed by Kranx.

Click on gamingcar then click to "Top Defense" (my new game) and then look into credits
1/5. A very run-of-the-mill repetitive game with no effort or creativity whatsoever. A recycled questions, outdated graphics, and 50% of the clickable area is white void. A thousand other quiz games do it much better. ;)
"why i upgrade over and over again? what "da" point?"
It is more like tower defense style - you have to build and upgrade from the beginning of every mission. So you can replay any mission to try another upgrade strategy and reach more rating/score.
About point: station reactor can be overloaded to take more energy in the current battle. You can distribute energy to enable and upgrade weapons. But after mission/battle we have to turn off overloading, because reactor can blow up in this case...
