How to play

• The world: monsters are living data left behind by a fallen, highly advanced civilization, sleeping in ancient crystals called Arc-cores (Archive Cores) among its ruins. Your Arcbracer, a bracelet with six Arc-core slots, holds your monsters and projects them into real bodies, one at a time; your phone is its screen.
• Explore the ruins room by room. Walk through a doorway to go to the next room. The map in the top corner shows where you've been; the red room is the boss.
• Doors lock when wild monsters appear. Beat them all to open the doors again. The sign over each doorway shows the reward waiting in that room (a gold Arc-core Shard is XP for your party). Walk over coins and berries to pick them up; berries heal.
• Move with WASD / arrow keys, or the thumb-stick on touch.
• Attack with 4 moves: left click, right click, Shift + left click and Shift + right click (or J K L ;), or tap the move buttons. Moves auto-aim at the nearest wild monster.
• Swap monsters with the SWAP button or Q. In a fight the action keeps going while your next monster is deployed, and swapping has an 8 second cooldown. The Arc-cores under your monster's health show the whole party's HP.
• HP carries over between rooms. If your whole party faints, the run is over. Fainted monsters get back up with a bit of HP on each new floor.
• Recruit rooms (an Arc-core on the map) let you pick 1 of 3 monsters to join your party, as many as your Arcbracer has slots for. Release monsters from the Party screen in the pause menu.
• Level up by beating wild monsters: the monster that's out gets full XP, the rest of the party half. Leveling up recovers more of a monster's lost data, and some transform once they've recovered enough. An altar deep in the ruins can take a fully grown monster even further.
• The shop (yellow on the map) sells healing and relics for coins. Treasure rooms (white) hold a free relic. Relics are artifacts of the old civilization: they last the whole run and change how your moves work.
• Beat a monster as a boss to unlock it as a starter for future runs.
• Beat the boss to open the stairs to the next floor. Clear all 6 floors, each a new area, and beat the final boss at the top of the Starlit Spire to win the run.
• Endless runs never stop: the floors keep coming and keep getting tougher. See how deep you can go.
• Esc or P pauses (or tap the phone), M mutes. Gamepads work too.
