Popup Dungeon is a procedurally generated roguelike with several inspired  twists. The first is that you can make anything and the system will balance it.  Want nyancat’s face on bullwinkle’s body wielding a tommy gun that shoots ice  beams? It can all be made through their system. The second is the unique art  style, creating the a game for PC that feels like it took a dungeon master a  long time, a lot of cutting, and several reams of cardstock to create.
