Dungeon of the Twin Fates

There are many different types of adventurers, but they are all connected by a thread of destiny: 

entering a dungeon, trying to survive and reaching the reward that awaits them at the end...

The player controls multiple characters locked in separate dungeons, but connected to each other. One character's actions also influence those of the other. In every dungeon there is a chest. The player wins if all characters are on their respective chests. Some dungeons have special rules that the player will have to discover. Good luck!
