QuantumJump — Portal Hop uses a quantum cyan-electric palette of deep oceanic midnight blues shot through with bioluminescent portal energy and electric-field cyan shimmer. It is a portal-based infinite platformer where players jump between platforms, teleport through portal pairs, collect power orbs, and avoid dark-matter hazards. The game offers 12 starting lives, giving players ample opportunity to improve before the session ends. Provided entirely free of charge. Our fundamental commitment: we collect no personal information whatsoever.
Everything stays on your device. No data is sent to any server. No account needed.
We do not collect, store, process, or transmit:
We store only your best score under qj_best using browser localStorage. This exists only on your device, is never transmitted, and can be cleared via browser Settings → Site Data → Clear.
No cookies. No sessionStorage. No IndexedDB. Only one localStorage key for your score.
This game is 100% free. No purchases, no virtual currencies, no loot boxes, no gambling, no prizes. All scores have zero monetary value.
QuantumJump generates portal pairs as players progress. Entering one portal of a pair teleports the player to the linked portal with upward exit velocity. A 40-frame invincibility window after teleportation prevents immediate re-entry. Portal and platform positions are generated procedurally client-side. No position data, portal usage, or run statistics are transmitted externally.
