Hop on every tile to reach the flag! Use the Arrow Keys or WASD to move. Each tile has a dot, indicating how many times you need to step on it before it sinks. You need to step on EVERY tile before reaching the flag. 

The more dots a tile has, the more times you have to step on it. Each time you step on a tile, one dot will be removed.

If you get stuck, press R to restart the level.
