good job with the game! Here comes some cirticism :D
I think the controlls need to be a bit less "smooth" if you know what I mean, there seems to be some mouse smoothing and when you start and stop moving there is a delay. Other than that, shooting the robots were very fun. I actually enjoyed the unprecise gunplay. I just wish the level were a bit less linear, It seemed to be only be one way to traverse the map with big collissions blocking me from going a different way.(these collisions also blocked bullet fire which was a bit anoying).
I really liked the opening when you are at the train and the train is actually moving. Good voice acting too!
