Shardswing

Shells drift in from every side in waves. Break them for shards, which fill a bar that grants a card about once a minute: pick one of three (or reject one you never want again), from faster swings and a heavier mace to shockwaves and combo abilities, or a "?" card that lists every outcome and its chance.

Every fifth wave a boss arrives: seven bosses that move, call in shells and fire bullet patterns you must dodge, with orbs your mace can knock back at them. Beat one for a rarer card, up to a second mace on its own tether. Minibosses break into the waves, every tenth wave the arena changes (twelve maps with bumpers, saws, pillars, wind, ice and moving obstacles), and a shop between stages sells drones, shields and an aura for that run's shards.

Between runs, spend shards on a 26-node upgrade web; complete it and Reforge for a permanent bonus and a second weapon, the Anchor. Play the Daily Gauntlet, the same run for everyone that day, or switch on Heat modifiers for a harder run and a bigger reward. Prisms, earned by play only, buy cosmetic looks, or open a geode holding a random look you do not own yet, odds shown first. Looks never change how the game plays. Progress is saved.

Mouse: move the mouse to move your core; the mace follows on its tether. Circle the mouse to swing it. Your first click locks the pointer to the game; Esc frees the mouse and opens Settings (pause).

Ability: press Space or E (or tap the ability button on screen) once a combo of cards unlocks one.

Touch: drag a finger to move; tap the ability button to use your ability. Settings offers a relative drag and a finger offset. In boss fights, lifting your finger pauses the game. The phone's Back button opens Settings.

Keyboard: Space or E uses the ability; Esc opens Settings; Enter starts the next run from the results screen.
