Tower of worlds

A mysterious tower that existed forever. Many people have entered it to ascend to higher levels and reach the top, but most of them fail. Each floor is a completely separate location in sub dimensional space, where people have to live, do quests and get better. Those who pass the quests may get the reward and go to the next location. The legends says that those you reach the top will get whatever they want, so it's tempting. It's a very dangerous journey, will you handle it?
