How to play Dunjen! Fast action card discard game.

About Dunjen, from BoardGameGeek:

A fast-paced, fantasy-flavored card game of chaos, sabotage, and dungeon-building. Dunjen is a quick and chaotic card game where players dive into a cursed dungeon and race to be the first to escape. Each turn, you'll play a card that matches the current biome or twist the game with powerful spells and special effects. But beware! Not all players want to help. Hidden among you may be adventurers with their own agendas, curses ready to strike, and monster cards that change the tides. Strategy, timing, and a touch of sabotage are your best weapons. Dhift the biome. Reverse turns. Force others to draw. And when the time is right… drop your final card to seal the dungeon and win. -description from the designer
