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.
