Big Tall Small is a cooperative puzzle platformer controlled by one player. You guide three different heroes through the same level and must bring every hero to the portal. A level is not complete when only one character reaches the exit; all three must make it.
Core controls
Use the arrow keys or A and D to move. Use W or the Up Arrow to jump. Press Space to switch between Big, Tall, and Small. Press R whenever you need to restart the current level.
The best basic routine
- Study the full level before moving.
- Identify which obstacle belongs to which hero.
- Move crates and unlock doors before sending anyone into the portal.
- Park each hero in a safe position before switching.
- Send the least flexible hero through first when the final route is ready.
The hard-level version expects careful timing from the beginning, so do not rush the first jump.
Why switching matters
Only the selected hero moves, but every hero remains affected by gravity. This makes positioning important. A hero left on a crate or another character may fall when the support moves.
