>Taste the Quarters to make sure they're legit.

They taste like metal; you're not really sure what illegitimate quarters taste like though?

> Search the floor for a trapdoor

The carpet has no visible cracks, and you don't seem to be able to pull it up with your bare hands.

>Use QUARTERS on QUARTERHOLE

You try putting one QUARTER into the hole in the DOOR; just putting it in and holding on to it does nothing, but when you finally let go of the quarter, letting it slide in like it would go into a vending machine, you hear some mechanical clicks deep inside the door and suddenly a metal plate shnks into place just inside the hole before you can try putting the other QUARTER in. You give the knob an experimental turn, and find that this DOOR is now unlocked.

STATE SAVED.
(Whenever something meaningful happens, the STATE is SAVED. A majority of the commands entered being ">REWIND" will cause time to revert to the last time the STATE was SAVED. This can only occur once per update, but can be done on consecutive updates to go back several STATES if desired. It mostly means you don't need to worry too much about doing something irrevocable that makes a win condition impossible.
You can also, at any time, request a list of the existing SAVED STATES, which will be presented in reverse chronological order, i.e., the order they will be returned to if ">REWIND" is selected multiple times in a row, and each of which will include a brief description of what event caused the STATE to be SAVED at that time.)
