Card-based Doom roguelike

Nightmare is a card-based roguelike game that takes place in the Doom universe. This was an idea for a real card game, but instead it became a web browser game.

The game uses cards for everything. With a set of cards you form a room, which may contain items, weapons, monsters, etc… There are just two ways of moving forward: 1- Killing all monsters 2- Finding an exit tile. You must click on tiles to pick them up. Empty tiles will increase your ammo and you have to be careful when you click on the monsters. Try to kill them as fast as possible or they will hit back.

As you pick different weapons you can switch between them hitting 1, 2,…7 as you would do in Doom.

The goal is just to move through dungeons as far as you can using your equipment wisely.
