@jacobingalls Thank you very much for your suggestion! In fact, we did design the outlines of various items and the corresponding number of grids that fit them, but in order to increase the game's difficulty and let players themselves realize the fit between item shapes and grids, we did not add this hint. Regarding the proposal that the number of items far exceeds the number of boxes and items need to be removed, I think it's great! This involves more of a psychological game with greedy security officers, and if we can continue to develop the game in the future, I will definitely consider this point! This was also an important idea in the last level I designed that was deleted: transporting the luggage of gangsters or the super-rich, where the excess wealth and limited space force players to deliberate.
