What would make the game better in my opinion: think about how to improve the mechanics of shooting by the player (looks interesting, but looks a bit buggy when you move the mouse beyond a certain radius from the castle, and also the player gets tired of shooting at chickens for so long); add a victory screen :D and maybe a scale with level progression (like in PvZ, for example).
What I liked: I really liked the graphics, simple and cute, the sound, and also the idea. Good job on the tower defense game!
Can I ask you, if you don't mind, to give a rating to our game too? I'm afraid that the ratings are few and the final score will go down :(
