Developer Matt Kap has released a playable demo for Windows of his retro-flavored exploration platformer Castle in the Darkness in the form of a prologue. Those who dislike playing demos because they spoil the main game, fear not! This is a separate scenario chock full of action. I explored a bit, too and found what I think was a bloated Double Dragon brother attacking me with drumsticks.

Readers seemed very excited by the mix of Megaman, Metroid, Castlevania mechanics seen in previous trailer. Players can expect all that and more in the full adventure in 2013 with over 15 hours of play, and according the the Greenlight page will be "the (cheap) price of most games' DLC!"

Those satisfied with the demo or the trailer can vote up Castle in the Darkness on Steam Greenlight.
