I really liked this idea of delivering blocks to your turrets! The polish was really good on this game!
There was some bugs with the lid of the box launching me up in the air occasionally.
It would be nice if there was some feedback around the button presses, like a noise or something to indicate something happened. As now, it's silent and the effect takes a few seconds before you notice anything, so it's hard to tell if the button press does anything.
Overall, great job! Impressed you did this within a week.
