That’s a great first try! To be honest, this game can bore me out of my mind, and I tend to create games I want to play. Considering this and the questionable control scheme, finishing at all is an achievement! Congrats and thank you for that! :D
And thank you for the ideas! I remember rushing a lot, trying to get this game out on time for a game jam, so some questionable decisions were made. If I were remaking this game now, I would resort to a more casual approach where crates spawn in big bunches and player has some time to sort things out before orders start coming. Kind of what Wilmot’s Warehouse did, but a tad more challenging.
