Trapdoor: Trust Nothing
The sneaky platformer
Free · Designed for iPad. Not verified for macOS.
Trapdoor is a platformer that lies to you.
The floor looks solid until it isn't. The door waits patiently, then runs. The ceiling has opinions. Every level hides a trick, and the only way through is to get got, laugh, and try again.
WHAT'S INSIDE
- 96 hand-built levels across 4 worlds, each with its own betrayal
- World 1, The Sneaky Platformer: falling floors, popping spikes, runaway doors, fake doors, portals, bounce pads, blinking platforms, gravity flips, and a mirror mode that swaps left and right
- World 2, The Keymaster: the door is locked, and the key lies too
- World 3, The Chase: things that move, things that hunt you, and the ones you can stomp
- World 4, The Double: two of you, one set of controls, and both must make it
- Instant restarts, because you will be restarting
- A journey map that saves your progress and remembers your best run on every level
- A death counter to brag about, or not
- English and Spanish
HOW IT PLAYS
Tap left and right to move, tap to jump, reach the door. That's the whole game. Getting there is the hard part.
MADE FOR KIDS, HARD FOR EVERYONE
Built by a dad in Malaga for his five kids, then made harder because they kept beating it. No ads, no purchases, no accounts, no data collected, and it works offline.
Every level has been verified beatable. When it feels impossible, it isn't. It's just lying to you.
