Having 1,000,000 hero power is pretty popular, but most experienced players have reached hero power exceeding 2,000,000 hero power!
The maxiumum hero level in Questland is 100. At this moment we are not planning on adding any more levels to the game. We believe that creating new, exciting in-game features is more beneficial to the game, than adding new levels.
Those features will guarantee a long-term engaging gameplay, whereas setting up the level cap higher will only be fun for few weeks, until it is reached again. That's why we focus on adding new, cool features that will allow our players to compete, rather than duplicating what is already in the game.
