WORLDSTACK vs Hallowkin

Behind every door, a new law of physics. Open one, and that law joins your run. WORLDSTACK is a colourful, surreal action roguelite. You are the Keeper, carrying the Last Star your light, your health, and your score through unstable pocket worlds. Each world ends at three floating doors. Every door adds a rule to your active stack: lower gravity, flood the world, magnetise metal, let fire spread, wake sleeping hazards, or double your score while making the Last Star fragile. Rules don’t just stack, they interact. Low gravity softens landings so glass floors survive. Fire meeting floodwater fills the world with steam. Magnetised metal near the Star redirects lightning. Your run, your rules, your own beautiful disaster. • 32 world-bending rules with real interactions • 8 designed world archetypes, procedurally rebuilt every run • 12 visually distinct door families • 5 guardians whose fights respond to your active laws • Special events every fifth door: repair, remove, fuse, upgrade or take a risk • Every completed run becomes a constellation you keep • A shared daily seed and rotating weekly missions • Missions, achievements and earnable cosmetics • Fully playable offline with no account • One-handed portrait controls • Reduced flashing, reduced shake, large-text and left-handed modes, plus adjustable sensitivity The doors are patient. The doors are waiting.

Death is not the end. It is an introduction. Hallowkin is a survivors-style horde game. You move and dodge; your weapons fire themselves. Monsters pour in from every side until the ground is thick with them, and if you last long enough, the chapter's boss comes looking for you. Then comes the part no other survivors game does. BEFRIEND WHAT YOU BEAT Defeat a boss and you do not simply move on. Offer it spirit, pass its trial, and it awakens as your kin - a companion that fights beside you in every run that follows. Return to that chapter later and its finale rises again as an Echo of the friend you made. EVERY CHAPTER FIGHTS DIFFERENTLY Chapters are not reskins of one arena. The Moonlit Meadow opens wide, with room to run and nothing to hide behind. The Moonlit Road funnels the whole horde into a narrow corridor where dodging is barely an option. The Haunted Forest closes in around you and never lets go. Each one brings its own cast of monsters, its own mid-boss, and its own finale - and more chapters are on the way. KNOW WHAT IS HUNTING YOU Wisps, moonbats and goblins early. Ghouls, wraiths and grave-shades later. Somewhere in the middle, a Brute shoulders through the horde with a chest you want and a lunge you do not. BUILD A HERO THAT LASTS Level up mid-run and choose your upgrades as you go. Between runs, spend gold on permanent hero levels, awaken more kin, and stock Moon Charms so one bad run never ends a good streak. PLAY IN SHORT SESSIONS Runs last six to ten minutes. Hearts refill on their own while you are away, and clearing a chapter for the first time refills them completely. No forced ads to keep playing. No pay-to-win - everything that makes you stronger can be earned. The night is full of monsters. Some of them are going to be your friends.
