This comment is really unnecessarily harsh. Their GDD made perfect sense to me upon the first reading. Your criticisms seem to be based on misunderstanding, e.g., dividing the year into 24 half-months, and giving the player a certain amount of stamina during each time period would be trivial to code. And the game doesn't go from a survival game to a tycoon game, the actions just become more powerful. I grade a lot of papers with my job and I don't see evidence of AI writing. These are cool ideas that are well-reasoned.
Let's be more supportive of our fellow jammers and give them the benefit of the doubt if you don't understand something! Or just ask if you need clarification about parts of their submissions!
