Interesting game! Graphics are nice, simple cutesy graphics. It shows that a lot of care went into it! The gameplay itself is fine, has a dead simple loop that gets quite satisfying once you get into a rhythm, even if once you've done 1 package you basically played through the whole game.
I'm just not sure about the UI. Hiding everything behind buttons probably isn't a bad idea, but the scheme kinda is here I think. It makes sense, for the Comment to be under the key C, or Destination to be under D, but for me It just doens't work. I would MUCH rather have just directional keys. Like the left menu opens with A, right weight menu opens with D, that sorta thing. The way information is presented is also a bit weird. The timer should be a thing that is always visible and reminds the player to hurry up. Hiding it kinda makes it a bit useless, like sweeping your problems under a rug kinda deal. Having all information under the comment except direction (and I guess weight if you dont know it by heart) feels weird too. I feel that the concept wasn't to make a hard game, but it just feels too easy with it. In Papers Please for example, all the data is in a different part which you need to double check, which is fun. And the datas are in a nice in-universe things like passports and not UI elements like here. I haven't got a single clue on how to try to better this UI design but it just doesn't work that well. The number thing is a nice touch, I liked that.
