IGTAP's secret level
Beyond the numbered courses that feed your clone economy, IGTAP hides at least one extra challenge that players call the secret level or bonus level. It has no achievement of its own on the Steam list, no store-page mention, and no official walkthrough — everything known about it comes from community videos and player posts. That scarcity is exactly what makes it a badge of honour for the players who complete it.
The clearest documentation is RJPlaysGame's "IGTAP Level 5 (Secret Level) - 28.1 seconds", a completion run whose title doubles as a challenge statement: under half a minute of near-perfect platforming. jake the dog's "IGTAP HOW TO DO THE SECRET LEVEL" and Joel's Videos' "IGTAP bonus lvl" cover the same ground from a discovery angle, showing how players find and access the level in the first place.
This page summarizes what those community sources establish without republishing step-by-step routes or coordinates. If you want the exact path, the videos above are the primary sources and are linked by title throughout the wiki's community coverage.
Course 5 and the developer's own hint
The secret level's strongest official-adjacent clue comes from the free web build. Players there hit a wall at the fifth course: the opening jump seemed impossible without a red-blue polarity switch that the demo never provided. The developer responded directly in the galaxy.click comments, confirming that course 5 "is not really part of the demo" and that the end-of-demo upgrade box would normally be where you swap blocks.
In other words, a fully playable course existed beyond the demo's advertised content, gated behind a movement ability players had not yet earned. Whether the community's "secret level" is that same gated course in the Steam release, or a separate construction, is not officially documented — but the developer's comment proves the concept of deliberately withheld level content is baked into how IGTAP is built.
The Steam achievement list confirms five Vman courses do exist in the full game: Deja vu (course 1, 12.6%), Getting Faster (course 2, 9.2%), Half done! (course 3, 7.2%), igtapithon (course 4, 5.6%), and Waow... so fast (course 5, 4.7%). Any discussion of a bonus level has to be kept distinct from this official five-course chain.
What the videos show
Watching the community runs paints a consistent picture. The bonus level is a precision platforming gauntlet in the spirit of the hardest late courses: tight jump chains, hazard-dense corridors, and a layout that punishes hesitation. RJPlaysGame's 28.1-second clear suggests a compact level where every movement is scripted by muscle memory, much like the recorded routes you build for your clones.
Discovery is the first hurdle. The "HOW TO DO THE SECRET LEVEL" framing of jake the dog's video implies the entrance is not signposted — players found it by probing the edges of the map, the same behaviour that uncovers IGTAP's secret upgrade pickups. Once inside, the challenge is pure execution.
Rewards are the murkiest part. No Steam achievement tracks the bonus level, and community sources in this wiki's research set do not establish a specific watt or clone payout. It is plausible the level exists purely as a skill test; treat any claimed reward as unconfirmed.
Bonus level, bonus area, B-Side
Three hidden-content terms circulate in the community and are easy to conflate. The bonus level is the secret challenge course covered here. The bonus area is the dark overgrown garden outside the facility, tied to the escape achievement The greatest adventure is what lies ahead — Lazy's "I Finally Beat The BONUS AREA in IGTAP" refers to that zone, and its video title likely feeds some of the naming overlap. The B-Side is a separate, harder community-documented challenge set whose official status is unconfirmed.
Each has its own page in the Hidden Content section. If a video says "bonus lvl" without context, check whether the creator is inside a course-style level or out in the garden before you trust it as a source for either.
Should you chase the secret level
The bonus level is aimed squarely at players who have already squeezed the main game dry. The Vman course chain tops out at 4.7% completion for course 5, the escape achievement sits at 5.4%, and a no-achievement secret level attracts an even smaller crowd — you would be joining the rarest club in the game.
Practically, the same toolkit gets you there: full movement abilities, patience with precision platforming, and a habit of checking every dead end and high ledge in each course. Speedrun-adjacent players will feel at home, since the level's short, technical layout rewards exactly the route-optimization mindset that IGTAP's clone system trains all game.
If you complete it, you will have done something the achievement list cannot even measure — which, for a game this fond of hidden depth, feels entirely on purpose.
