I think there's two major problems with this game:
-First it is terribly classical: Zombies-TNT-Puzzle-Game
-Second it is very easy.
The thing is that you see that the creator of the game tried to make something new but the fact that there's only a few materials where you can put your TNT and that after all, it's still a very classic gameplay seen and seen again.
The good points are:
-The ambience
-The Graphics
The music and the cartoon graphics gives a very "funny" ambience that is very pleasant.
