I think it might have been fun if 4g had decided to do the entire game in base-12. NGU Idle is a game based around numbers and number-patterns. Duodecimal, having a radix divisible by seven numbers (1,2,3,4,5,6,12) instead of decimal's four (1,2,5,10), probably has many more aesthetically-pleasing patterns. It would be hard to adjust, but I think that would add to the experience, too.
I have lost my save-data three times in two days. I was getting around this by saving-to-file, but somehow my latest save-file has no data in it. Halp.
This is the kind of game which I can replay once- or twice-a-year, despite its heavily dialogue-based nature. Gotsukaresamadeshita, Mezzanine-tachi-sama.
That's a good idea why have i never done that
