I really, really enjoyed this game! Like, it's so stylish, and yet, so simple. Guns are fun, and satisfying to use, and the suddenness of death when you fall out the carriage is hilarious lol. I love the research mechanic too. Adds some good depth, whilst keeping it simple.
It is a little too easy to mess up when you first start though - If you have too little xp to buy bullets and you miss too much, you can't progress any further ad your only option is suicide. Some kinda of really basic weapon with infinite ammo or regenerating ammo may be helpful just in that case? Or even just a stick to prod enemies as they get close to get a little xp back?
But overall, an ace game! Looks good, plays good, is good:)
