About this game

HAMMER FROG
A frog is stranded at the top of a tall tower of blocks, and the only way down is through it. Stand on a block, swing your hammer, and knock it out sideways — the frog drops one level closer to the ground. Do it again, and again. Clear the whole tower and the frog dives into the river far below.
The catch: you can only knock out a block when the space behind you is open, and every block you remove changes what you can reach next. Pull them in the wrong order and you'll strand yourself with no move left. Each stage is a compact spatial puzzle — read the tower, find the loose thread, and pull it free.
And every single stage is built to be solvable. No dead ends by design, no luck required. If you're stuck, there's always a better line — and if you make a wrong move, just undo it and try again.
HOW TO PLAY

Move and turn the frog around the top of the tower
Tap the block under your feet to hammer it out behind you
Turn to aim: a block flies out the way the frog is facing
Empty the tower level by level until the frog reaches the ground
