Added forced-combat rooms

Some rooms will now lock you in until you've defeated all the enemies or survived for one minute. The visual lock-in effect is an example of the intended aesthetic style, but not necessarily full-quality final art.

Because of how intentionally strange some parts of this game are, it can be difficult to tell what's a bug and what's intentional. Please report anything that stands out as anomalous, even if you're not sure it's an accident.
