FAQ
16 quick answers before you play
What is Big Tall Small?
It is a puzzle platformer where one player switches between three different heroes to solve every stage.
How do I control the heroes?
Move with A/D or the Arrow keys, jump with W or Up, switch heroes with Space, and restart with R.
How many levels are included?
The game contains 20 progressively difficult levels, including five expert stages at the end.
Can the game run fullscreen?
Yes. Use the Fullscreen button above the playable game window, then use the same button or Esc to exit.
Does the game save my progress?
Yes. Unlocked levels, completed stages, sound, and music settings are saved locally in your browser when storage is available.
Do I need to download anything?
No. The complete game runs directly in a modern web browser without an installer or additional software.
Can I play on a phone or tablet?
Yes. The game includes responsive sizing and on-screen touch controls for compatible mobile and tablet browsers.
What is Big best at?
Big is the strongest hero and can push crates that the other two characters cannot move.
What is Tall best at?
Tall has the highest jump, making this hero useful for elevated keys, platforms, and vertical routes.
What is Small best at?
Small moves quickly and can fit through tight crawlspaces that block Big and Tall.
What do keys and locked doors do?
Collecting a key lets the active hero open a nearby locked door, so choosing the correct route order matters.
How do springs work?
Landing on a spring launches the active hero upward, helping you cross hazards or reach high platforms.
What happens when a hero touches spikes?
The active hero is defeated and the level restarts, so use controlled jumps and careful timing near spikes.
How is a level completed?
Big, Tall, and Small must all enter the portal. Reaching it with only one or two heroes is not enough.
Can I restart a level at any time?
Yes. Press R whenever a route goes wrong or a hero becomes trapped.
Are the levels difficult from the beginning?
Yes. This version uses harder layouts from the opening levels and gradually introduces more demanding teamwork, hazards, and route planning.
