About

Déjà Vu

One level. Just one. It looks easy: hit the button, reach the door, done. Then you play it again... but something has changed. Right is now left. The floor melted under your feet. The door started running the moment you got close. The second you yell "same level?!" you finally understand the game. Déjà Vu is a sneaky trap-platformer. Every run shows the exact same scene but quietly breaks one rule. Your goal never changes; the only thing that changes is the new game the level is playing on you. Each of the 70 levels is a fresh troll: reversed controls, invisible floor, rising lava, flying instead of walking, doors that flee, winning by dying, standing perfectly still to survive, swimming underwater, flipped gravity, time that moves only when you do, outrunning your own ghost, carrying a live bomb, and much more. The moment you feel certain is the exact moment you lose. Retro pixel visuals, a crisp VT323 font and smooth, instant-response controls. No ad walls, no forced interstitials. When you're stuck, tap the light bulb in the top left: if you want, watch a short rewarded ad to unlock a hint and a "Skip Level" option. But it's fully optional — with no ad available the hint is free and the flow never breaks. The choice is always yours. Features: - 70 handcrafted troll levels, each with its own rule-bending twist - Traps that change every run: reversed controls, vanishing floor, rising lava, flight, portals, underwater, flipped gravity, frozen time and more - Precise, instant-response platforming - Retro pixel art with a clean, readable font - Landscape; full iPhone and iPad support - Turkish and English - OPTIONAL rewarded ads only — NO forced or interstitial ads - Hints and optional level skip when you get stuck - Plays offline, no account or login required
