Lets hope my players are smart enough.

Thanks for the input! There are some fights that purposefully cause split party, yes, but there is a way to prevent the boss from aggroing until the whole group is ready if you can find it. I do have monsters aggro through any number of open doors. And good call on the changing states, the easiest way to do it is to hover over the wall or tile and press 1 or 2 to open or close it. Glad you liked it.

This is really well done. On my initial solution several fights (including the boss fight) would start with a split party, which would be scarily intense trying to solve the puzzle to get your group together while fighting. Also, when you run this do you have monsters from the next room come at players if the doors are open? What about 2 or more rooms ahead? And you should make it clear in the instructions for anyone new to TTS that all you have to do to change the doors is to right click and change state. Thanks for sharing!
