5/5
man, this is probably the best defence/rpg mix out there, it's a rather great mix the the player's ability to control the hero. A sequal would be nice, so far i find that the hardest level was, level 4, but i am on level 7. Level 6 was really easy all i did was make like 100 centuars in middle near the base, of course dug the whole middle out... Then i set maximum amount of traps >.<
