At first im in need to say, that this game is one of the best Tower-Defense-games i ever played.
But i also have some criticism: please make me able to buy a better "send wave"-key, it would make this game much better.
the best tipp is, to use the dog as tank: just go in the corner next to the dog-shop and stand between the car, your dog and the darkness...u wont be killed and will gain ur kills really fast without using repellent
very fun game, but a little bit to easy if u have best equip
very very good game, i really like it!!
especially the balance of strength is made very good.
another tipp for boss number 3: just throw fruit at him (use the d key) and he will eat, so u can hit him
