I think this concept is really interesting! I was a little confused by how the planning screen worked. I feel like I should have been able to drag blocks onto the map and place them but I wasn't able to. Whenever I clicked on the left floor area, the number after x would go down so I assumed that something was happening. When I clicked Try, I could see that blocks were placed in the 3d space but I wasn't able to acomodate them. I think the concept is quite neat though, I might give it a retry in case I missed something. Great job overall!
