A pretty entertaining game, says the hour of gameplay I put into this. Could of been many more hours if there were more than 3 different zombies that did more than just shamble toward your castle. What I really didn't like was the difficulty gaps and overall how difficult the game was. The very first few waves were appropriate but then it suddenly gets much harder, though once I got the elf bombers the rest of the game was far too easy, and once you get the turrets in combination with the elf bombers, you have nothing left to do but pick up candy canes and watch as there is nearly no need to participate in the fight.
Overall, the game was too short with odd difficulty gaps and eventually just too easy once you purchase all the upgrades available.
