Super cool game! At least it was cool when I played it because I won and stopped global warming ;) yeah bad pun, sorry. Anyway, I'm a huge fan of idle games so this was right up my alley. My first run I spent all my money on research and then couldn't get any more money to spend on advertising, so I was at a bit of a stand still with no way to win. I think once you realize you have to spend money on advertising in order to get money, the problem is solved. One way I think you could combat this is to have a small amount of advertising already at the beginning so that you can still get a little bit of money in case you do something dumb before you know how to actually play. Great job though!
