Yes, but game needed a way to improve difficulty somehow, once you get guns it gets quite easier. I think either AI needs to use guns more effectively or they need to increase emeny count that try to chase you and hit you, give handicap for being ahead.
The game tries to increase difficulty by letting you choose handicapped characters to start off with, but as long as you get guns it's easy. If you select characters that don't have guns, game us difficult but not fun.
That being said even the first few runs you take at it. It's quite fun and worth 6$.
