Thousands of Heroes

The spirits that uphold the foundation of the world. An anomaly occurred among those spirits. And chaos befell the world... Young spirit mage Alto suddenly lost the ability to communicate with the spirits "The spirits are acting strange." What is happening to the spirits? In order to calm the disturbed spirits, Alto decided to set out on a journey to seal them. A serverless, asynchronous, and multiplayer rogue-like game. By sharing the main player's dungeon ID (a string) through chat or other means, anyone can play that dungeon and support the main player. Support players can reveal hidden passages visible only to them, send item codes (strings) to provide missing items to the main player, and when the main player opens a door, they can convey the unlock code (a string) to the support player to open that door. This creates a loosely interactive exchange between the two parties. Wouldn't it be fun to easily...
