Cool game !
My comments:
- I had a bug several times where I put a people at the right place and the people above it goes back on the ground, even though it was placed correctly. I'm not sure it's a bug, maybe I did something wrong without noticing
- At each level I need to click on the "People needs" window again. I think it would be great if the window remained active in between levels?
- After a few levels I find the puzzles a bit repetitive, even with the slight increase in difficulty. I could be great if there was a visual change or a higher tower, or something like that. I didn't make it to the end of the game, so I don't know if I missed something.
