Cute art-style with awesome music. I like the UI and the reload UI. I like the looting the civilians gameplay aspect as well. I like the robot enemy flying over the train but no matter what I did I could not climb over the train carriage or was able to damage the robot.
For improvements, there is no feedback when firing the gun, taking damage or doing damage. Enemies destroy into pieces when they die and that's cool. I think game needs more polish on these aspects.
