I liked that there was a tutorial section but putting a fairly harsh time limit on a tutorial for a game that relies on you understanding that the workers will only go to whatever is closest to them seems a little harsh. You should give your players a chance to get the hang of the mechanics before giving them time limits I feel.
after I failed the tutorial 3 times though I worked out that they only go to the closest thing, picking them up and dropping them seemed to do very little to help guide them, and they can't walk through the spaces that are indicated in red.
Then I was in the game and realized it was going to be a monumental task if I didn't somehow get more workers (which I'm guessing is the biscuit factory?) basically it felt like I had to place every building in the perfect position to get them doing what I needed them to do which it turn felt like it was removing my freedom from the game.
All that being said those are only points I didn't enjoy about the overall gameplay, the visuals (though I'm not convinced the butler wasn't ai generated), audio and general vibe of the game were all very solid and impressive to pull off in a week.
Generally an excellent inclusion in the jam! well done!
