Big Tower Tiny Square 2 is the direct sequel to one of browser gaming's most respected precision platformers. You return as the tiny square, still fighting your way up an enormous tower filled with increasingly devious hazards. The sequel builds on the original's room-by-room structure but introduces more complex obstacle combinations — bouncing projectiles, collapsing platforms, and tighter corridors that demand pixel-perfect movement to survive.
Move with arrow keys or WASD and jump with Space or Up. Wall jumps are essential and must be mastered early — many sections require chaining them in quick succession. Each death resets you to the start of the current room, not the whole tower. Take a breath, study the room's pattern, and commit once you know the route.
