Ok, Just to set a couple of things clear.
To the creator of the dragonslayer, Your game is a defense game, its REALLY not the first, and seriously wont be the last.
-Inspiration is something you take from everyone, you dont just simply do random shit hoping for good stuff, you'll be influenced even if you like it or not.
The author did probably see a couple of defense games, not nessicerely yours though.
As for the last reviewer, i once again must repeat myself, it probably is similiar to others like this, but i think this one in itself is original.
Ok, Now for a review.
Graphics; They were good, even though 2D, and fairly balanced through the whole thing.
Sound: Meh, Bad artist.
Zeth dont know how to make good music, hang him, now.
Style: I liked how you set everything up, even though its cliche and overused, It's still a pretty good setup and you get loads of spare time thrown away.
Violence: Blood, Death.
It works.
Overall: It's a good game with n00b music and the music kills the game :|
