Escape or Die 2

Solve puzzles and beat the clock in the thrilling Escape or Die 2! Get ready for extraordinary logical thinking in this game! Your main task is to escape. And the only way to escape from here is through the small window above the ceiling. Put a ladder there, and you'll see that the window is locked. I don't think anyone left you a key. But don't be discouraged. Find a couple of retorts and chemical research vessels, and make an acid that will corrode the metal lock. Hurry up, or time will run out, and you'll die!
