Something got messed up between last version and this update. I thought the balance changes would make for an interesting challenge to return to, so I downloaded the game, made Glorpina her first order on day 1 and was left mouth agape at the fact she gave me a C on a burger that otherwise looked perfect. Cue a lot of stubborn testing and I was finally able to get an S rank by cooking the bottom bun *just* before the first appearance change. It seems all the other first customers of the day suffer from this issue, and additionally getting an S rank on Captain on low-grav still seems impossible and I'm not sure why (I could do more testing but I don't want to repeat the first customer's order every time so I opted not to).
Aside from this, customers also seem to take into account ingredients on the cooker when rating their order, so you can wind up getting an F rank out of left field because you forgot to trash something before handing over the burger. If this works like I think it does technically I guess it means you could give the customer a seemingly empty plate and get an actual score for it, but like I said before I've had enough for the time being.
Overall, I think the update is cool, but it's a shame that it's so broken. The level select and gallery are undoubtedly nice but it also sucks your effective progress gets reset if you don't start from the very beginning every time instead of the score just carrying over from your best attempt at that day.
Still, you guys are going in the right direction. If I were to suggest something it would probably be the ability to add custom customers (custom-ers, hah) or something, along with an endless mode you'd have a practically finished game in hands. Best of luck on future projects as well!
