I like the main gameplay loop and the addition of color not just scale for the different packages. Could see this expanding quite nicely with other changing machines and larger scale belt lines. It is a bit unforgiving as I know I had failed the first time on a few levels as I was trying to read the prompts and the wrong product made it to the end. In the context of the jam I like the timer but maybe have it so certain products need to be delivered in a specific time instead of everything?  Also had a little trouble with the level where the size needed changed as a box was entering the out-shoot so I got penalized for something i couldn't possibly have changed. I really like this type of game though and would love to see this expanded further in the future!

I just completed all 6 levels! I think the size of middle and small are quite similar, so maybe player will failed the level because of this issue. Overall it's really smooth and polished, and I liked your idea and nice logo too!

Very pleasant palette and good tutorial!

really fun game! very well done tutorial too! it shows off the relevant mechanics without being too unforgiving or dragging on! great work! 

Interesting concept, I feel like a restart level button would've helped a lot so that I don't have to wait when I know I'll fail. But I can see the potential in it, particularly when you have multiple things to manage
