graphics and the gritty vibe are great but the challenge with enemies is that you only have two shots which is enough to kill one slow enemy and the reload but having to stand still to reload while there are two enemies getting close to you is just hard, the fast enemy is also a challenge because you have to get up high to reload or your dead because he can take more than two shots. Adding the ability to reload while walking would be a game changer (literally). My last critique is that aiming with the arrow keys is weird, if you could aim with your mouse it would require more skill, because of missing shots, and adding a headshot feature would be great because you only have two shots and need to make them count. Adding either one of those features would reduce the difficulty quite a bit, if your looking to do that.
