This game has more potential. Maybe a story could be added instead of adding 3 stages where you do the same exact thing with different weapons and different mobs.

Nice game could be a little more to upgrade and a bit longer but it´s pretty nice the way it is.

An enjoyable game, I liked it that there are 3 campaigns with different characters and enemies - but in the end, the campaigns are almost the same except for the spells. Also, as others mentioned, some readjustments of enemy strength etc might be necessary. And also stopping the game after victory or defeat - it's a bit funny to see enemies continue attacking me after I won (when killing bosses for instance), or my health regenerating after a loss, missing an animation of my tower collapsing :)

i like i spend the most of my day playing it but its a bit easy and it need some real achivements

People here would like it much more if it had some real achivements.
But again, that would be just a way to force people to play until the end. The second and third campaings really wasnt interesting at all before you beat the first.
