"Everyone knows you can't fight a boss without a party." As a Dark Souls player, I disagree...
However I think the game is pretty fun, I love the dialogues! When it comes to gameplay I would change the color of player bullets I know they are not the same but they still look similar enough to distract in the heat of battle. I think it would be better if they were something like blue or something like this, but not gonna lie I will back to this game later just to see the ending, great humor! ^^
