A Night at the Museum Forever

This is one of the earlier time travel games, being introduced in the first IFComp.

You are in a museum of time, trying to take its final treasure, a diamond ring. But its existence is not secure yet; you have to ensure it will be there when the time comes. So you travel back and forth between several time periods trying to create the diamond and glass cover and find the setting for the ring.

Some actions that you take don't seem like they'd actually work in real life. Other actions can be relatively straightforward.

Good for fans of puzzle time travel games.
