Jetblade - .01
Jetblade is a 2D platforming game in the style of the Metroid and Castlevania series, but with procedurally-generated maps.
Jetblade's goal is to bring roguelike-style procedural map generation to the 2D exploration-oriented platforming genre. It supports an extensive, highly moddable procedural map generation system with room for almost arbitrarily complex maps. The game is not remotely complete yet; right now it can make maps and you can explore them, but there's nothing actually in them and occasionally it'll make a one-way tunnel without realizing it. Contributions are welcome; Jetblade exists at least in part to give people a large project that they can contribute to while learning the ropes of software development.
