Great job submitting a game! You've set up a good atmosphere here and I like the concept of managing the train. Its got a great arcade feel too it imo. The pick up / drop / use system can get a little annoying since they all share a key. I can understand embracing simplicity / being creative with controls but the actions are exact opposites of what you want to do in a moment (drop vs use). I think if you separated those actions the game would play much smoother. Awesome that you took some time to include sound and class "bang" text coming from the guns, definitely made the combat more exciting! Thanks for participating!
