So I softlocked myself while cooking because I mashed Space.
You can't rush cooking I guess :)
So I restarted, taking care not to press Space too fast, and the game went on as normal.
I played until Mokou had... nothing to say. The game music had stopped too by the time I reached this point- perhaps the looping was not properly implemented, but it still cemented what was going on. When I got to the point where Mokou fell into silence, I went through a dozen more task cycles... And every time I felt a weight, and it grew heavier and heavier.
And a vague feeling of existential dread got to me. The best thing is, I knew what was going to happen. The storytelling here is just very effective.
