Machinarium

After you get into the basement (above you there is a bar and the previously flooded offenders), take a sledgehammer and break the small window (it’s on the right), put the sledgehammer in place and take out the key from the broken window. We return to the elevator (to enter it you need to press the button to the right of the door) and on the right we open the cabinet built into the wall (with the key), from it we take the freezing bottle and return back to the basement (to exit the elevator you need to move the cursor almost to the very bottom of the screen and an arrow will appear). We use freezing on the castle hanging there, take a sledgehammer and break the castle - the hooligans have escaped, the “girl” has been freed.
