It wasn't a One Hour, it was actually made in response to a challenge Lys made a long time ago to make a complete CBS game in a month.
But you're right. I remember that at the time I was pondering using auto-close, but decided not to because I didn't want the player to miss any information. But in retrospect, they should have been auto-close, because it otherwise just extends things needlessly.
If I decide to remake the game, that's one thing I'll do. I also need to better design the formulas, because I heard from someone else that it begins to break down pretty badly at the high levels.
