Game play in this game was great, the background, the cinematic's and the story line was all great. But I found the difficulty the first time through was to easy, I know there is hard mode but the game doesn't have enough to go through again. I easily beat the game with the AK-47 no problem and without the use of the power ups. My suggestion is either adding enemies with different ability's maybe some enemies that have projectile attacks and what not. I also found that sometimes shooting single bullets a click was unresponsive and would take two clicks to shoot 1. Other than those minor problems I loved the game :]
