Thank God for Adult Swim in both its animated form on Cartoon Network and its digital incarnation on the triple W. The wide selection of web games these twisted weirdos offer is worth checking into on a regular basis.
Adult Swim's newest free web game is Dungeons & Dungeons. In this Castlevania clone you play a whip-wielding dominatrix who uses assorted sexual devices to whip, beat, electrocute and burn assorted foes. Why? Because they like it!
