It's an interesting concept. Jam-wise I'm not sure that first world war counts as Industrial Revolution, since many people agree the Second Industrial Revolution firmly ended in 1914, the first year of the war. But I suppose you could make an argument there. The sounds and graphics are good for a game jam, as is the gameplay. My thoughts on if you want to take it further would be that it absolutely needs some better directing of the player, as when you first spawn in it's a little unclear what to do. An option to change the inverted controls would be nice, but overall it's a unique game with a lot of potential to be something great.
