Dungeons and Don't Do It is a DnD parody, or satire about DnD... Namely, how players always find a way to do something stupid and mess up the DM's world.
(For those of you not familiar, DnD is a role-playing game, where players take on the role of an adventurer on a quest, and have great flexibility in choices while the DM- "Dungeon Master" creates the story for them.)
While it is possible to play through this game seriously, it isn't the point! There are plenty of silly options and random generated results to go along with the theme and lead your character through a wacky adventure. Beware about the RNG, though! Some options are much more difficult to pass than others.
