super cute idea!

I think it's cute. Though, I felt a very real lack of feedback in the game. I didn't know when the game started whether the store was open or not, then when I opened and I took a ticket, I didn't know which piece corresponded to which description, then I didn't know what to do with the pieces until after I read your description below the game, and it took me until just now typing this on the submission page to look at the screenshot to see I should be able to put the label on the box. I made a robot that I wasn't sure if it was right or not, it got all boxed up, then I left the workbench, and when I went back into the workbench interface the box was missing, so I had to guess whether it was intended design or if the box was just gone. If I got into the flow of it and learned what everything meant, I would probably have a better time with the game, as it's kind of in the style of the Papa's Pizzeria games as far as I can tell, and I like the idea of putting the toys together (It also seems to me this could be your interpretation of the "unfinished projects" part of the theme and I like your creative take), but it really just wasn't clicking for me at first.

After going back in and trying it again, it was fun once I knew everything, and like I've read in the other comments you already know about the parts going missing after finishing a robot or two, but the idea is there. Props to you for making things work enough to convey your idea - I imagine it's tough to code it to recognize when the robot arm is attached to the body, or when the body part is in the bin, etc.

I had a little bit of trouble figuring out how to ship things at first but I see the vision! I'm sure there are a lot of cool ideas cooking underneath for this game! The art style is V cute! 
I ran out of parts and I wasn't sure how to get them back. My unsolicited desire: I wanted to smash the table and have all the parts fly up from the bins and then just swipe with my mouse to "collect" as much as I could before they all fall back and then have them sprawled out so I can easily pick and choose what I want! Maybe that doesn't fit the vibes though 

Could do with a quick in-game tutorial. I found the UI a little confusing and difficult to grapple with, but despite that I really enjoyed the game. I loved the day transitions outside the window, really cool. Very happy to play it again if you do patch it after the jam is over :)

Really cool implementation of UI.

The place feels really good

There are a lot of improvements possible in the UI but it is really great and mostly intuitive already. I did not need much reading to figure it out.

The final boxing I did once but after that the parts in the boxes went missing not sure if bug or skill issue.

Congrats on releasing a cool game!

I like the idea. Very cute and the style is fun. I think there's definitely some aspects that can be adjusted, sorting layers of objects, making sure things respawn and UI ordering but I think it's a good proof of concept. Good job!

I respect the ambition! The first time I played, I didn't realize I needed to make a full robot (not just the parts that the customer requested) which confused me for a long time. I ran into a glitch where all of the bins went empty, and wouldn't refill no matter what I did, so I couldn't do anything after my first package. Cute game, could use some polish and more clear instructions.

It has really great fresh ideas on an old a proven game genre but it could use clearer instruction and a tiny bit of UX changes post-jam.
I would have placed the boxes for parts directly near the assembly table and I would have had parts less on top of each other perhaps. Also, I would give more instantaneous feedback if you did good/bad and why. It has a lot of potential. I'm glad I got to playtest it! Good work.
