We are set for the eleventh annual 7DRL Challenge. GET READY!

The challenge will run March 7 to March 15, you are invited to take part and create a roguelike game in 7 days, starting from whatever you want but producing a new, complete, playable game at the end of the week!
The 7DRL challenge breathes new life every year into the roguelike development community, last year we had 248 challengers, don’t miss this opportunity!
In 2005, the roguelike community established a yearly event, the 7DRL Challenge, in which all the world is challenged to create a roguelike in a one-week span.
7DRL Challenges are NOT about being a fast coder, but rather proving you can release a finished, playable roguelike to the world. There is no winner of the challenge, but rather all those who finish are honoured for their work, the criterion is completeness.
You CAN use external libraries, game engines, pre-existing generic code/algorithms, pre-existing generic art, etc. You can even start your game from an existing game, if you are willing to turn it out into something unique, you must however say what resources were reused.
Challengers may use the International Roguelike Registration System to accept the challenge once it starts; you can also check the reviews for last year entries here!
