It took me ages to find out that I could move in the air and solve level 2. The rest of the levels were perfect regarding difficulty. Die a few times, but never extremely hard. It was a nice experience.
The game is great, only the ninja's are just unbalanced. I only build ice towers in the hope i freeze them. But that only happends 1 out of 10 times. I tried level 12 6 times now and still haven't got it perfect.
