It's simple but the timing from click to shoot makes it difficult to aim

this game sucks plain and simple.

good. it's fun . ^^
I like simple game like this.

Simple, playable and repetitive. Losing is inevitable due to the numerous hordes of dragons that waited until you finished your castle and then decided they didn't want you here. Kind of a dick more on those scaly bastards but such is life. Also, some achievements/awards/medals would be nice.

the game starts out hard to fast make lvls so that as the lvls progress it gets harder, also maybe getting points for killing the dragons and then using those points at a store in the game to buy defense for the tower would be a good idea.
