Not too bad
While the animation was kind of lacking, it was still fun to play because it had some good stuff. It was funny how a lot of the enemies just kept eating each other. It sure made my job easier! What I did not like was that I do not think I was able to try again without reopening the page. I click what the guy is saying and this sign tells me to use my mouse which I do, but nothing happens. You also could have given the monsters some better designs.
It was still quite fun to go around with that crane and manuever. It seemed like an original idea to me, but it's something so obvious it probably has been done before. This game can get extremely difficult, especially when you have to retreat so often. I don't know if there is any difference between the red and green enemies. Hey, those are Christmas colors!
