Splunky: A Rogue-Like Platformer

Splunky is a rogue-like platformer where instead of going left and right or up, as you usually do, you go down into caves. It's randomized so Derek has kind of set up parameters of what a level can look like, and then he randomly generates them every time you play. There's a bunch of secrets in Splucky that you have to try to puzzle out. And it also sort of co-wrote on the tales of Dark Souls and difficulty becoming cool again in games.
