Thanks for the feedback. During development, there was another button that upgraded a separate Congo Drone(TM) that dropped packages periodically and would increase in frequency as the player upgraded it, however the drone ended up dropping a box every 5 minutes or completely filled the screen with them. With the deadline approaching, I ended up cutting it out of the game and if I were to develop it any more, I would add that feature back in. Furthermore, having a feature that clicked on the boxes for you was another idea, but that one didn't come to fruition as the programming for that was a bit beyond me. I like the idea of adding things to the space to visualize the upgrades. That way people can get a deeper sense of progression by seeing their upgrades in a more diegetic way.
