"The Hero Trap is a frenetic, roguelike dungeon-crawler. A glorious treasure has been promised, but all who’ve sought to attain it have found only death. But you have a plan! You can gather the souls of great warriors past, who’ve failed where you now seek success, to aid you on your epic quest. These heroes are strong, but not invincible--their spirit energy can only withstand so much punishment before returning back to the ethereal ooze." (Quoted from the game's Kickstarter page.)
*The project reached its goal last night on Kickstarter.
