This expansion as few more levels to the original game. Their designs are thouhtful.
The level designs are thoughtful. They really want you to think about your defense in a different way each time you change of level.
The bad aspect, you have to unlock your speed potion and destructive mine again. There is not a lot of levels, and most of them are harder than the first version.

Is it worth you're money? If you liked the original one, why not? It's almost the same.
Oh, there's a lot of different background stage. The challenge are there, you'll be able to play the same stage you've played before, but this time there is going to be some snow, so the ground we'll be a little bit slippery.
No new tower, that's a shame.
No new tower, that's a shame.
No new towers, that's a shame.
