Parallel Dungeons

Here is an excerpt from Parallel Dungeons' Steam description:

From the creator of N Step Steve and Bee Magic comes a roguelike game with a unique twist.

Each of those health bars you see in the middle of the screen is its own universe. The universes all exist independently from each other, except when they don’t. Each item you use affects all of them, except when they don’t.

Don't worry if this all sounds daunting. The game has been carefully designed to be simple to understand and is full of tooltips that explain the less intuitive things (like what the “range” of a set means.)

There are four playable characters with their own play-styles, and each player has four unique dungeons that add additional twists. Can you beat all sixteen dungeons? Probably. Can you master all sixteen dungeons? Maybe.
