i agree with perita, pretty cool game but very generic. not too sure how the theme fits.

also, the game doesn't work on browser for some reason.

By the name of the towers, i assume the “enemies” are children and you have to feed them candy for trick-and-tricking, all night long, which is a pretty interesting twist on the theme.

Aside from that, it is a pretty generic tower defense.  There is nothing wrong with that, but i have nothing else further to add.

I like the 2D graphics, and the audio is nice. But it's a shame the 3D graphics are cubes.
I don't understand how you get money in this game. And it took me a while to understand the cost of each object.
Overall, the game is fun but I don't get the story at all, except it's on halloween. Maybe you lack of time?
