If you are genuinely getting stuck at this point, then I hope your puzzle-solving skills will dramatically increase as you continue through this game, because this does not bode well considering the difficulties of the next twenty-three puzzles. If you are struggling with this, there are many other “helpful” guides that will tell you how to move and look around.

Use your mouse and keyboard/controller to find and press it. Nevertheless, waiting twenty years is not the recommended solution.

Hint: Despite what the voice in your head says, you will not die of thirst if you keep waiting.
