How to play
Move with WASD, the arrow keys or the touch joystick — your hero attacks automatically. Collect XP orbs to level up and choose new skills and potions. Open treasure chests with gold, charge Thorn Sigils and hold out while minibosses arrive. Then beat the portal boss and go deeper.
Bosses on every floor
Minibosses crash into every floor and a portal boss seals the way down. Every attack is marked on the ground before it lands.
