## What is Pixel?

Collect every Pixel. Master ice, fire and traps. Reach the Plenum.

Pixel: The Challenge is a 3D puzzle game in the spirit of the great tile-based logic classics — completely re-built and yours to master. On every level you gather all the Pixels, find the right keys, and cross water, ice, conveyor belts and monsters until the Plenum portal opens.

The logic is grid-clear and deterministic, just like the classics — but the world is real 3D with smooth animation. Best of all: every one of the 80 levels is provably solvable. A solver works out each solution in advance and stores a replay. No level is down to luck. None is unfair.

ONE PRICE, THE WHOLE GAME
You buy the game once and everything is there: all 8 worlds, all 80 levels, from the first step to the final Plenum exam. Nothing to unlock, nothing to subscribe to, no currency, no energy timers, no ads.

WHY YOU'LL LOVE IT
• 80 hand-crafted levels across 8 worlds — every one guaranteed solvable
• Classic logic, real 3D — plan it, solve it, execute it cleanly
• Two art styles — switch between Voxel (chunky and bright) and Low-Poly (soft and modern) at any time
• Three cameras — third-person, first-person or top-down; see the puzzle your way
• Fair for everyone — chase 3 stars as a pro, or switch on Casual mode with no time pressure
• Stuck? Watch the solution — a built-in walkthrough shows the proven path
• 100% ad-free — no ads, no tracking, no pop-ups, plays offline

WHAT STANDS IN YOUR WAY
Keys and doors, water, fire, slippery ice, conveyor belts, bombs, teleporters, cloning machines, switches and buttons — and all sorts of monsters that move on their own.
