I really like the graphics on this one - clean and simple. Nice color scheme. I wasn't totally sure what the different polluters were so a little menu pointing out the different types of items could have been useful. I also couldn't tell if there is a way to be strategic with the items I placed or if it's just "luck of the draw". Maybe it'd be cool if there were a "pollution level" you had to monitor instead of a points system? in I think this idea has a lot of potential and it would be worth revisiting the gameplay. Great work!
I'd love some feedback on my game also!
