I ran into the same glitch of emissions reaching 100% despite implementing bike lanes/ trees/ sidewalks, but you all did a great job! I like the art style and the simple mechanics made gameplay intuitive and not over-whelming. I would love to get the full experience of my actions affecting the emission rate, but besides that, you all did a great job. I also really appreciated the tutorial. I think this is a promising game with many directions you could go in, but it is also successful as is with some minor bug-fixing!
