This time don't let any queens leave the orthosquare area.
Found two solutions to this challenge. One is somehow fast, another is somehow scenic. I'm not sure which was the one you had in mind, so, here goes the third challenge about the scenic solution:
Clear this room such way that no one roach and no one queen flee outside the boundaries of their original formation.
To be precise: no roach, no queen and no egg should ever be seen on column 7, column 13 and row 22. Queens can spawn on two southern tiles (next to green door and symmetric one), but again, those roaches must not escape.
