An amazing inversion of tycoon games. I love how reorganizing the calendar becomes this kind of adaptive and dynamic puzzle. The only improvements I can think of would be adjusting the spacing of the options, since some of the options come out a little too soon after the previous ones for them to be much use. And I would love it if you could leverage the puzzle aspect a bit more, maybe mandatory 'blocked-off' timeslots or ideas which lock in place and have to have each cell be completed fully before they can be replaced?
