No. Your weapons fire automatically. You only control movement — drag anywhere on screen, or use WASD or the arrow keys — which makes positioning and dodging the entire skill of the game.

Collect blue gems from defeated enemies to level up. Each level offers a choice of three upgrades, and every card shows your damage per second before and after taking it so the options are directly comparable. Certain combinations of weapons and stats unlock evolutions, which turn a weapon into a substantially stronger version, so choosing upgrades that work together matters more than taking the strongest single option.

The run ends, and you spend the cores you earned on permanent upgrades that apply to every future run. Dying is the expected way a run finishes rather than a mistake, and progress carries forward.

Splitters divide into smaller enemies when killed, so clearing them in a confined space can surround you. Chargers telegraph before rushing and can be dodged if you watch for the wind-up. Bombers light a visible fuse and explode a moment later — the ring on the ground shows the blast area. Bosses change phase partway through the fight and alter their attack pattern.

Every boss except the last drops a chest where it died. Walk over it and it opens: if your build already meets the requirements for an evolution you have not taken, the chest grants that evolution on the spot. Otherwise it gives a free level to one of your weapons. Either way it adds three cores to your permanent total.

The arena has no edges, so you can always run — but the game sends swarms at regular intervals: a ring of darts closing from all sides, a pack of chargers, or a wall of brutes. Those are designed to be fought through, not outrun, so a build with real damage matters more than speed.
