For the 2010 7 Day Rogue-Like Challenge, I wanted to do something a little controversial. Rogue-like games are typically from a top-down view, which makes a lot of sense when you want to represent the action in a 2D dungeon.
In a change from the normal view, Earl Spork is a side scrolling platformer. While there was, as hoped, some controversy over whether or not it really qualified as a rogue-like game, I think that it was very successful. It was turn based, grid world, and contained random terrain. On the other hand, there was no inventory system, which means no identification sub-game which is often cited as a primary feature of rogue-likes.
