Congratulation on this really great game. It was one of my favorites 🤩
The premise of the game is very simple and well known in many similar games with the controls being very intuitive. I really like how you used the theme because you have to remember what objects are in which box. Definitely a different approach to all the other games of the jam.
The only thing that bothered me a little bit was the box filling machine. The blue button was a little too slow for me. If I click it three times in quick succession, I hear the click sound 3 times, but it advances the items only 2 times. I would also love to change the items while the current one is dropped into the box.
The red "BOX" button is also confusing because I don't associate it with destroying the box. Maybe also add a bigger button to return to the other room. The "x" is a little small and the mouse pointer is not really indicating where the click is performed. Don't get me wrong, I love the mouse pointer, but it just doesn't fit for the small button.
I know that this gets against your game idea, but you could add different sizes for the boxes depending on the amount of objects in it, or the size of the objects.
PS: It's really interesting that you are selling dynamite. I have no idea what Samuel is up too, but it seems he is going to book a flight in "They Shall not Pass" game (https://itch.io/jam/5th-winter-game-jam/rate/1323102) 🤣🤣🤣
