Thanks a lot for playing and for the kind words about the pixel art! :) The day starts at the computer inside the kiosk: go through the door, walk to the desk with the computer and press E (or click it). There you can stock the shelves and press "Start day". And you are right, that was way too hidden. I noticed it myself, so in the main version of Kiosk Days there is now a small tutorial that walks you there step by step. Sadly I'm not allowed to change the jam version while the voting is running, so it has to stay like this until the jam is over.
