I really like the idea behind this game! Combining memory with exploration is a cool concept. However, movement in this game, especially of the scaled-down objects, was quite difficult. I didn't understand why I couldn't go up the overpass in the big environment, and wasted a lot of time on my first attempt trying to do so. Having to go around was slow and finicky, especially considering the time limit, whch limited exploration. I also couldn't figure out how to move the miniature buildings at first - I knew you had to click and drag them but it was difficult to figure out when you were able to pick them up. Perhaps some kind of visual cue when the buildings are clickable might be useful?
I also had trouble moving the buildings around and setting them down properly, due to the distance you had to be from them to move them and also the fact that they would often clip through the table. Another thing is that there was no way of knowing how to say you were done so the game could tell you whether you got the environment right or not. If it's supposed to be by setting the buildings exactly on the rectangles, unfortunately I was unable to do that. Even when I definitely remembered how it was supposed to go I couldn't set the buildings down exactly right and it always felt like they weren't rotated correctly.
Overall though, I can see the concept and think this game has a lot of potential. I hope you improve this one!
