Well, ya.. good game, well, actually great game. yes i would give a 4 out of 5, the reason is that some levels were too big and tower denses dont usually have levels THAT big. Anyways i think its a pretty good game and maybe you should make Castaway TD 2 with more choosable pets, abilities which use magic not only traps like backup stuff, gaining pets over levels, ability to change pets, and stat points to encrease your pets special ability. Still, good game.
