This is such a fantastic game. I love how you really throw us in without much to go on, leading to--at least, with me--a very fitting false sense of security and inevitable failure. As you'll read from my other comments I failed in the first run-through, but after restarting with some strategies in mind I did much better. I'm an environmentalist and vegan, a far cry from the way I grew up: totally apathetic and skeptical of global warming thanks to a heavily conservative, Fox-News-obsessed- family. I really got into this game and will more than likely return to it to see how quickly I can save the world again (lol). I hope this helps to inform other people about how important it is that we help change things, and soon. But I do think it would be much more realistic (and helpful to the cause) to highlight how animal agriculture has greater impacts on anthropogenic global warming than coal and gas-fueled transportation. (The name is gimmicky, but the data is tried and true: Cowspiracy is a documentary available on Netflix and all the sources are listed on cowspiracy.com/facts. I highly recommend it!)
One thing I struggled with as far as mechanics go: I played this in-browser on my Mac and a large part of the right side of the screen is entirely cut off when in full-screen mode. If I wanted to read what different "power ups" (so to speak) would do, I'd have to exit from full screen and scroll over. I also didn't realize there was a pause button until halfway through my second game because of this lol.
Just small things. Overall, absolutely excellent game. Thanks so much for it!
