Hyper Knight

Kill the enemies you encounter and clear the entire room to move to the next room. After killing all the enemies, you can advance to the next level through a portal that opens to the next level. As you kill enemies, you collect souls. You can sell the souls to the Soulkeeper to convert them into gold, which you can use to strengthen yourself. After some time, an arena will open where you can compete in one-on-one battles with other warriors.
