Very simple little lane/tower defence game. Nice style, easy on the eyes, easy to play (although the click-and-drag mechanic isn't immediately obvious).
Quite easy, and the same simple strategy works on every level. I finished the game without dying once. Not having to grind is very nice, but a little bit of strategic complexity (for example, some monsters with ranged attacks, or with the ability to change lanes, or something) would spice it up.
Nice cute cartoons, although I think having a final cartoon at the beginning or end (or both) of the final level would have made me a bit more satisfied upon finishing the game - probably would have been worth an additional half-star rating.
