Good shooting game
There are a lot of shooting games that are released on NG but this one was one of the best.
The difficulty level was well managed I think. Maybe it could have been a bit longer (with more levels). Also, it would have been nice to have an ending animation congratulating the cop for his good job. And maybe some funny stuff.
Also, the Bank could have had a better design. And we could have heard the bad guys agonizing when we kill them.
That are just some ideas for improving the game. It is already a nice one.
