Such a clever implementation of the teleport mechanism! I love how you have to choose which package to work on since they expire at different times.
The only problem I had is that it took me way too long to figure out what to do. Due to font color, size, and placement, the 1, 2, and 3 on the tables were really hard to see. My attention was drawn to the arrow keys and I didn't realize you had to press the numbers to switch between the packages. I also tried to use WASD a couple times instead of the arrow keys haha.
To fix this, I'd suggest making the 1,2, and 3 bigger and a more contrasting color. Also it might help to have a how to play screen with controls, or at least write the controls in the description.
But once you get the controls down, it runs really smoothly and works well! I enjoyed it!
Well done :)
