This is a very solid game. I can only find two downsides. First, stealth is optional for a while. I just killed everyone in sight and beat the level with easy eventually though. I am not sure if that's bad or good. Secondly, the controls are somewhat awkward, making trying to run forward turn into switching items if your fingers are in the wrong position.
Overall, this is a great game, give it a shot, you might like it.
