A fairly simple game, but no less interesting for it! I found it surprisingly addictive. I think it could benefit from some background music to make the experience feel more alive, as well as a little more polish in its overall presentation.
That said, I can definitely see the game's potential. With some further development, I think it could work really well on mobile platforms.
I'd also like to highlight how creatively you've incorporated the game jam's theme and limitation into the game. It shows great imagination and a good understanding of how to make the most of the constraints.
Great idea, great work, and a great team! Keep it up! =D ❤️
