In the past Pixel has alluded to the earlier iterations of Cave Story (even a near-finished build that got scrapped along the way), but he’s never released anything playable. Well, as of just yesterday… he still hasn’t released anything playable!
But he did release something almost as cool — a collection of screens and concepts from early in the game’s development. (You might remember him doing something similar with Guxt.) I love this sort of thing. It’s like a little window into the mind of a developer I admire.
Definitely check it out if you’re a Pixel fan. (Who isn’t?)
