You only steer.

Everything else is automatic, so every decision is about where to stand and what to take next.

1. 

   Drag to move

   Hold anywhere in the lower half of the screen and drag. Let go and your hero stops.

2. 

   Attacks fire on their own

   Your weapon and abilities trigger by themselves. Aimed attacks pick the nearest enemy; the rest circle you, sweep or strike around you.

3. 

   Level up, pick one

   Enemies drop XP gems. Every level-up offers up to 3 cards, taking turns between attacks (a new ability or a level for one you own) and stat cards like Armor or Crit Chance. An attack at level 8 evolves once you own its catalyst stat card.

4. 

   Coins stay. The horde resets.

   Every coin and key you pick up is saved the moment you grab it, so you keep them even when the horde wins. Between runs you spend them on the menu tabs.
