Smart game, good use of the limitation and I enjoyed it a lot!
The art could be more detailed (instead of the solid grey background) but overall great job!
Thanks! The background (the floor) is supposed to be concrete, so I get why it would seem like a solid grey (maybe you have a visual bug though?).
We also had to cut a few mechanics, so we didn't cover everything, especially at the bottom, that's something we would rework if we made a complete game!
