It's very good to see developers working on solving feature issues.
So I hope you'll keep working on the party switch system ^^.
I would love to see it made available for others in some way, as well!
In the demo, I got stuck between a locked door and a cat...Shi couldn't move because of the cat, and my doctor lady couldn't pass through the door. XD So, I soft-locked it in this use case. But the mechanic is interesting!
