No clicking. Just the mouse.

Your cursor is the sword. Move the mouse and the blade follows it, cutting whatever its edge sweeps through — there is no attack button, no combo, no cooldown to manage. Rest the edge on an enemy and it keeps cutting. Leave the mouse alone for a second and the blade takes itself over, going for whatever is closest to the core at 60% power, so the run keeps going while you don't. That is the idle half.

Hold the core

A crystal core sits in the middle of the arena and everything that spawns wants to chew through it. Clear a wave, take an Awakening — one of three cards that bend the build — and go again. Every kill drops shards; when the core finally shatters they bank, and they buy tiers on the sword and levels in the forge that no death takes back.

The demo is the first hundred stages

Hollow Steps, from stage one to the warden who closes it. The whole loop, not a slice of it:

• Thirty-two monsters — new trash every five stages, a new elite every ten, nine bosses, then the warden.
  
• A different floor every stage: moats, walled keeps, causeways over a chasm, spirals, pillar fields. And a different arena size to hold the crowd — stage 1 sends thirty bodies, stage 100 sends close to four thousand.
  
• The forge, where nothing has a last level, and as many sword tiers as your shards reach.
  
• Ascension from wave 25 on — melt the sword, the bank and the forge down into embers, each worth +12% damage and shards forever.
  
• Offline earnings, equipment off elites and bosses, all three difficulties.

The full game takes the same climb on through Fungal Deep and Bone Reliquary and then stops counting: endless waves, ninety-six monsters, and tier 100 at ×6.3T damage.

Played on your terms

• Three difficulties — GENTLE, NORMAL, FIERCE — switchable mid-run, applied to the next enemy that spawns.
  
• Save anywhere: the run in progress is inside the save file. Leave in the middle of a wave and pick it up from the title, at the start of that wave.
  
• Five volume sliders, four text sizes, three colour modes (red-green safe and blue-yellow safe included), high contrast, screen shake from 0 to 100%, and a switch for the light flashes.
  
• Every page plays from the keyboard. The blade cuts on contact; menus never do — hover only highlights, and a click or Enter commits.
