Rogue Legacy

A roguelike platformer where you control one hero at a time through a randomly generated castle. When you die—and you will—you pick an heir from three randomly generated descendants to continue the run. Each heir gets two traits: your barbarian might have OCD (enemies must be killed left-to-right), your mage could be colorblind (the world renders in grayscale), or your assassin might have gigantism (too tall for some passages). There are 35 traits total. Between runs, you spend collected gold on permanent upgrades like more health or new character classes. Progress carries over, so each death inches you closer to clearing the castle. The trait system makes failure entertaining rather than frustrating.
