If Powerhoof can make games like they can make trailers, then Crawl could be very good indeed. It's a same-screen multiplayer brawler, in which the player must avoid the traps and enemies activated by their ghostly friends. The concept is dramatically explained in the video, by a narrator whose hammy horror acting would make Vincent Price proud. Of course, as an indie game, it's also accompanied by some expressive pixel animations and a glitchy chiptune soundtrack.
Aimed at 2-4 players, one person takes control of the human, while the others play as ghosts. In order to stop their human victim, ghosts can possess traps and use magic runes to take necromantic possession of skeletons and undead creatures. Whichever ghost lands the killing blow is then given a mortal body, and must take their turn to survive the dungeon gauntlet.
It's a solid and fresh concept, which is increasingly hard to find in the growing same-screen multiplayer genre. If your interest has been piqued, you can find more details at the game's site , and vote for a possible Steam inclusion through the Crawl Greenlight page .
