Ninja vs EVILCORP has a rule that never changes, no matter how high you climb in the tower: every camera follows a pattern. Learn the pattern and you own the floor.
This browser-based stealth platformer by Rémi Vansteelandt places you inside a skyscraper owned by a corrupt corporation, working floor by floor to hack terminals and expose what's hidden. Detection means instant failure. The game doesn't give you a second chance when an alarm triggers - it restarts the level and asks you to try again with what you've learned. That structure turns every failed attempt into useful information about a path you now know better than before.
Read the Pattern, Own the Floor
Every level in Ninja vs EVILCORP is a compact puzzle dressed as a platformer. Guards follow routes. Cameras rotate on fixed cycles. Laser grids activate at timed intervals. None of these elements are random - all of them are readable if you take thirty seconds before moving to study the room.
Most players fail by moving too early. The impulse is to act on the first gap you spot in a camera's sweep. The better approach is to watch two full cycles: one to identify the pattern, one to plan your exact route through it. A floor that looks impossible during the first scan often reveals a clear path on the second. The difficulty of Ninja vs EVILCORP comes from reading pressure, not from the obstacles themselves.
How to Move Through EVILCORP's Tower
Each floor presents a new environmental layout. The objective is always the same: reach the secure terminal, hack it, and clear the level. The path to it varies - some floors require threading between overlapping camera angles, others need you to time a wall-jump perfectly to avoid a laser that cycles too fast for a ground-level approach.
The game encourages players to find alternative paths before defaulting to the most obvious route. Shortcuts exist on most floors - riskier paths that cut travel time significantly. Players willing to read the room carefully before committing will find that Ninja vs EVILCORP rewards confidence in movement more than caution in hiding.
Controls
Arrow Keys / WASD - move left, right, crouch
Up / W / Space - jump (hold to jump higher)
Wall contact + jump - wall jump to reach higher platforms or clear danger quickly
Wall Jumps and the Art of Not Getting Caught
The wall-jump mechanic is where Ninja vs EVILCORP separates itself from simpler stealth games. It isn't just a traversal tool - it's a speed tool, and speed matters because camera windows are time-limited. A well-executed wall-jump sequence lets you cross a danger zone in less time than a standard running path, which means you can slip through gaps in coverage that would be impossible at ground movement speed.
The slide mechanic works similarly. Dipping under a laser that's at mid-height is often faster than waiting for it to cycle off. Momentum-based play - chaining slides, wall jumps, and direction changes - is what speedrunning this tower looks like, and it's available to any player willing to experiment with movement.
Why Each Floor Gets Harder in a Satisfying Way
Ninja vs EVILCORP escalates gradually but without mercy. Early floors are designed around single camera sweeps and straightforward guard routes. Mid-tower floors introduce overlapping coverage zones where no single position is completely safe and you have to move during brief moments when multiple vision cones are simultaneously pointed elsewhere. Upper floors add timing dependencies between multiple moving elements, turning each level into a sequence problem.
The retry structure keeps this from feeling punishing. Failed attempts are short. The level resets immediately. You re-enter with the route memory of the previous run and usually a clearer idea of exactly which moment you mistimed. That feedback loop - attempt, fail, learn, retry - is what makes Ninja vs EVILCORP's difficulty feel earned rather than arbitrary.
