Very fun game! I have some feedback though:
- Since the game starts only when you finished stocking the first shelf, you can make it a lot easier on yourself by placing all the boxes right in front of where they should go before the game starts. You can even stock every shelf with just one item missing. Might be intended but it makes the first have of the game quite boring where you just play "normal" shelf stocker without customers, and the actual game super easy.
- Dropping (not throwing) a box makes you automatically pick it back up about half the time, was quite confusing at first as I thought there was some areas I wasn't allowed to leave a box, that was until I just started throwing them instead.
- Throwing a box while in stocking mode bugs the game out a bit until you press space to exit.
- The baby customer becomes almost (or always?) unbeatable later in the game, ran as fast as I could to where the baby was but got game over before I even saw it. Seems like you get too little time to find it in some cases later in the game.
Again, otherwise love the core gameplay and the artstyle, hope you keep polishing this!
