IGTAP — short for Incremental Game That's Also a Platformer — is an innovative indie title that merges two beloved genres into one endlessly replayable experience.
You are the only one — a lone runner tasked with generating an extraordinary amount of electrical power in a strange, industrial world humming with voltage. Short platforming courses wind through neon-lit corridors and spike-filled chambers. Every run you complete earns Watts, the currency of progress. Spend those Watts on upgrades, clones, and new abilities that let you earn even more.
Developed by Varii @ PepperTangoGames, IGTAP was originally built for Pirate Software's Game Jam 17, where the theme was "only one." The concept: one character, one world, one goal — but infinite scaling potential. The game blends the satisfying number-go-up dopamine loop of incremental / clicker games with the kinetic thrill of precision platforming, light Metroidvania exploration, and even speedrunning depth.
Players quickly discovered that IGTAP rewards both passive idle strategies and active speedrun optimisation. Casual players can deploy a clone army and watch Watts pour in automatically. Hardcore players can shave milliseconds off each course run to amplify production multipliers — making IGTAP one of the most unique incremental platformer games available to play online today.
IGTAP isn't just another idle clicker — it demands skill, rewards optimisation, and keeps evolving the longer you play.
Every course run earns Watts. Spend Watts on upgrades that increase passive production. The incremental loop is tight and satisfying — IGTAP's core economy rewards both idle players and active grinders equally.
Unlock clones that replay your best path with pixel-perfect precision. In IGTAP, your recorded runs become automated income — the better your route, the more Watts your clones generate passively.
IGTAP features tight, responsive controls with coyote time, wall jumps, dashes, and advanced tech like dash-wall-jumps. Shaving seconds off your course time directly multiplies your Watt income — speedrunning pays off.
The IGTAP world isn't just a series of isolated levels. New movement abilities unlock shortcuts and reveal hidden areas with secret bonuses — reward for curious explorers who wander off the beaten path.
Upgrades in IGTAP aren't just stat boosts — many open entirely new gameplay possibilities. Jump upgrades, dash unlocks, and production multipliers each reshape how you interact with the platformer courses.
IGTAP plays great on both keyboard and gamepad. The incremental platformer experience is smooth regardless of your input device, making it accessible for casual and competitive players alike.
New to incremental platformers? Here's everything you need to know to start generating massive Watt income in IGTAP.
Move right, jump over obstacles, and reach the end of the first platformer course. Even a slow first run earns your starting Watts in IGTAP. Don't panic about spikes — checkpoints are frequent.
After your first run, open the upgrade panel. Purchase your first clone — it will replay your best recorded path autonomously, passively generating Watts while you plan your next move.
Save up for the Dash and Double Jump upgrades early. These IGTAP movement abilities don't just help you move faster — they open entirely new routes and previously inaccessible course areas.
Once you have dashes and double jumps, revisit earlier courses. Faster runs mean your clone army earns more Watts per loop. IGTAP rewards route optimisation with exponentially better passive income.
Look for secret bonus zones off the main path. IGTAP's Metroidvania elements hide bonus power nodes and shortcuts behind ability gates. Exploration multiplies your total Watt production ceiling.
Higher courses yield dramatically more Watts per completion. Master the Dash-Wall-Jump technique to access elevated sections. In IGTAP, the hardest courses offer the best incremental returns.
Optimise faster with these pro strategies.
In IGTAP, dashing into a wall and immediately wall-jumping propels you straight upward — far higher than a normal wall jump. Essential for Course 5 and above.
IGTAP's clone income is based on your recorded course time. A 3-second run yields far more passive Watts than a 30-second run — speed is money.
Before grinding a course, check if a new ability opened a shortcut. In IGTAP, shortcut routes can cut course time by 50–80%, transforming your idle income overnight.
IGTAP's final major upgrade resets course times and re-runs everything in near-darkness for a massive Watt multiplier. Save this for when you're confident in your routes.
Blue and red spikes in IGTAP are directional hazards. Only certain movement states let you pass over blue spikes — explore carefully to find the cave and jungle sections.
Use the in-game reset option for individual courses to re-record a cleaner, faster run. Useful after unlocking new IGTAP abilities that enable better route splits.
