The Tale of an ASDF

Once upon a time,  a hippo named Qwerty won the lottery and spent all of his winnings on an ASDF(Adventurous Sophisticated Dungeon of Fun). However, some of his employees responsible for cleaning the dungeon got lost. In an attempt to help his employees, he hired you to go inside and find them. However, a magic jinx has been placed on the dungeon. In order to enter, you're going to have to play by the rules it has.......

You must  play as one of three characters in a dark room where you have to roll a dice. This dice determines the monsters that you have to fight inside the dungeon. The goal is to keep rolling until you find one of the lost employees in the dungeon.
