Great game, glad to see an update, found some bugs I figured I'd help troubleshoot.
After some of the Vivian cuddle scenes, I noticed abnormal behaviour. Quick testing:
Front hole = brief view of the corridor while talking with Minty
Become gas = normal
Go deeper = normal
Feed her + escaping immediately = normal escape, then, the second you walk out the door, the cuddle scene starts again, and the corridor shows her door missing, suggesting it's still actively being interacted with.
Repeated testing shows that this also happens if you escape a few turns later. It does not happen if you use the rear entrance, so I suspect you misplaced some triggers.
