Seems like there's a decent amount to do and it's cool that it has a feature for you to try and discover new recipes. I could see myself getting pretty hooked on this for a bit. Well done for only 1 week!
Edit: I came back for more, and ended up unlocking all the recipes. I made it to about 10% progress before it just felt like I wasn't really making any increasing progress, so I felt like it would take a little while to beat. Couldn't quite seem to increase my popularity, but maybe I stopped digging just before the diamonds. Fun game in any case, it had me wanting to try to beat it and I got to a point that I felt like I more or less did, I just wasn't sure I wanted to spend the rest of the time finishing at that point.
Fun game, nice cute graphics, fun Japanese references. Very well done for 1 week.
